Changes 5.18.1:
* B has been upgraded from 1.42 to 1.42_01, fixing bugs related to lexical subroutines.
* Digest::SHA has been upgraded from 5.84 to 5.84_01, fixing a crashing bug.
* Module::CoreList has been upgraded from 2.89 to 2.96.
* Starting in v5.18.0, a construct like /[#](?{})/x would have its # incorrectly interpreted as a comment. The code block would be skipped, unparsed. This has been corrected.
* A number of memory leaks related to the new, experimental regexp bracketed character class feature have been plugged.
* The OP allocation code now returns correctly aligned memory in all cases for struct pmop. Previously it could return memory only aligned to a 4-byte boundary, which is not correct for an ithreads build with 64 bit IVs on some 32 bit platforms. Notably, this caused the build to fail completely on sparc GNU/Linux.
* The debugger's man command been fixed. It was broken in the v5.18.0 release. The man command is aliased to the names doc and perldoc - all now work again.
* @_ is now correctly visible in the debugger, fixing a regression introduced in v5.18.0's debugger.
* Fixed a small number of regexp constructions that could either fail to match or crash perl when the string being matched against was allocated above the 2GB line on 32-bit systems.
* Perl v5.16 inadvertently introduced a bug whereby calls to XSUBs that were not visible at compile time were treated as lvalues and could be assigned to, even when the subroutine was not an lvalue sub. This has been fixed.
* Perl v5.18 inadvertently introduced a bug whereby dual-vars (i.e. variables with both string and numeric values, such as $! ) where the truthness of the variable was determined by the numeric value rather than the string value.
* Perl v5.18 inadvertently introduced a bug whereby interpolating mixed up- and down-graded UTF-8 strings in a regex could result in malformed UTF-8 in the pattern: specifically if a downgraded character in the range \x80..\xff followed a UTF-8 string
* Lexical constants (my sub a() { 42 }) no longer crash when inlined.
* Parameter prototypes attached to lexical subroutines are now respected when compiling sub calls without parentheses. Previously, the prototypes were honoured only for calls with parentheses.
* Syntax errors in lexical subroutines in combination with calls to the same subroutines no longer cause crashes at compile time.
* The dtrace sub-entry probe now works with lexical subs, instead of crashing
* Undefining an inlinable lexical subroutine (my sub foo() { 42 } undef &foo) would result in a crash if warnings were turned on.
* Deep recursion warnings no longer crash lexical subroutines.
Updated lang/perl5 to 5.18.1
- When the source line is logged (option -s), an empty line above
  helps to see which source line belongs to which warning.
- PKGSRCTOP is a known variable. It is used only in the top-level
  Makefile.
- Arbitrary tool names may be added to TOOLS_NOOP.
- In the top-level Makefile, the alphabetic order of the SUBDIRs
  may have a single exception.
Changes 5.0.5:
This release sets the error return properly when a screen descriptor read fails, and fixes minor API documentation bugs.
update security/ipv6-toolkit to version 1.4nb1

code was added to fix the compiler uninitialised warning (thanks!),
but the distfile name didn't change since it was packaged originally,
so do the DIST_SUBDIR dance, and bump package version to nb1
note update to security/ipv6-toolkit version 1.4nb1
Remove patch that's no longer needed
Changes 1.2.3:
This is a bug-fix release.
The pkg_info command is an internal detail and therefore should be
hidden behind the ${RUN} macro, just like all the other commands.
_PKG_DEBUG and _PKG_SILENT have been deprecated since 2007.
Updated graphics/giflib to 5.0.5; multimedia/ffmpeg to 20130827.1.2.3
Typo
Small grammar fixes in the comment.
Up to now there was no way to get help on pkgsrc internal variables,
like _PKG_VARS. Since there exists documentation on these internal
variables, it should be found by "bmake help".
Fixed pkglint warnings.
Fixed a pkglint warning.
Changes 1.12.16:
Bug fixes
* Set the correct orientation for simple boxes with a negative scale factor.
* Fix the creation of the shading dictionary in PDF.
* Fix a crash in PDF when incorporating an image with CAIRO_EXTEND_PAD.
* Avoid upscaling bitmap fonts if possible.
* Fix an assertion failure within the mempool allocator for shared memory.
* Fix allocation size for CFF subsets.
* Export cairo_matrix_t for GObject bindings.
* Fix a double free in the Quartz backend.
* Fix origin of GDI StretchBlits for the Windows backend
* Fix error propagation for requests to create a similar surface with
  negative size.
* Fix complex clipping of trapezoids with regions
* Stop leaking the image data when loading PNGs
* Fix unbounded operations with a clip mask through the span compositor
* Add missing checks before rendering to a finished surface - so we return
  an error rather than hit an assert.
* Prevent an assertion failure when creating similar GL surfaces larger
  than supported by hardware.
* Prevent a double free of a similar image under Windows.
Changes 0.9.20:

General:
- Misc substitute_closure() fixes.
- Build fixes.

Documentation:
- gtk-doc boilerplate integrated.  Docs are built now, but
  contain no contents.  By next release hopefully we have
  some content in.  Enable using --enable-gtk-doc.

GObject and Introspection:
- Added harfbuzz-gobject library (hb-gobject.h) that has type
  bindings for all HarfBuzz objects and enums.  Enable using
  --with-gobject.
- Added gobject-introspection boilerplate.  Nothing useful
  right now.  Work in progress.  Gets enabled automatically if
  --with-gobject is used.  Override with --disable-introspection.

OpenType shaper:
- Apply 'mark' in Myanmar shaper.
- Don't apply 'dlig' by default.

Uniscribe shaper:
- Support user features.
- Fix loading of fonts that are also installed on the system.
- Fix shaping of Arabic Presentation Forms.
- Fix build with wide chars.

CoreText shaper:
- Support user features.

Source changes:
- hb_face_t code moved to hb-face.h / hb-face.cc.
- Added hb-deprecated.h.

API changes:
- Added HB_DISABLE_DEPRECATED.
- Deprecated HB_SCRIPT_CANADIAN_ABORIGINAL; replaced by
  HB_SCRIPT_CANADIAN_SYLLABICS.
- Deprecated HB_BUFFER_FLAGS_DEFAULT; replaced by
  HB_BUFFER_FLAG_DEFAULT.
- Deprecated HB_BUFFER_SERIALIZE_FLAGS_DEFAULT; replaced by
  HB_BUFFER_SERIALIZE_FLAG_DEFAULT.

Changes 1.1.1:
* Fix typo in header search path for local libraries
