Fix build failure on NetBSD-5.1

pkglint now warns about broken dependencies like >=x.y.*
Version->4.135
According to a report from Michael Kopp in private mail, this needs
pango at runtime or it won't start.

Note: it isn't clear to me where this comes from or what the
circumstances are (the package source does not appear to refer
directly to pango) so I'm going to use buildlink rather than just
DEPENDS (which might be sufficient) out of paranoia.

PKGREVISION -> 3.

Changes 5.18.2:
* B has been upgraded from version 1.42_01 to 1.42_02.
* B::Concise has been upgraded from version 0.95 to 0.95_01.
* English has been upgraded from version 1.06 to 1.06_01. This fixes an error about the performance of $`, $&, and c<$'>.
* File::Glob has been upgraded from version 1.20 to 1.20_01.
Bugs fixed:
* Perl 5.18.1 introduced a regression along with a bugfix for lexical subs. Some B::SPECIAL results from B::CV::GV became undefs instead. This broke Devel::Cover among other libraries.
* Perl 5.18.0 introduced a regression whereby [:^ascii:], if used in the same character class as other qualifiers, would fail to match characters in the Latin-1 block.
* Perl 5.18.0 introduced a regression when using ->SUPER::method with AUTOLOAD by looking up AUTOLOAD from the current package, rather than the current package’s superclass.
* Perl 5.18.0 introduced a regression whereby -bareword was no longer permitted under the strict and integer pragmata when used together.
* Previously PerlIOBase_dup didn't check if pushing the new layer succeeded before (optionally) setting the utf8 flag. This could cause segfaults-by-nullpointer.
* A buffer overflow with very long identifiers has been fixed.
* A regression from 5.16 in the handling of padranges led to assertion failures if a keyword plugin declined to handle the second ‘my’, but only after creating a padop.
* The construct $r=qr/.../; /$r/p is now handled properly, an issue which had been worsened by changes 5.18.0.
Updated lang/perl5 to 5.18.2
