- Convert to USES=autoreconf
- Remove WANT_GNOME
- Patch configure.in and Makefile.am to move config and m4 directories out
  of the libltdl directory.  This prevents rerunning autotools+configure
  during make build.
- Convert to USES=python
- Convert KNOBS to proper OPTIONS
- Add LICENSE
- Drop gmake dependency
- Use DATADIR instead of BHOME variable
- Simplify and separate configure and build stages
- Rework do-install target a bit
- Add .pyo files
- Use SUB_FILES instead of patch
- Update plist
- Update WWW
- Bump PORTREVISION

TODO: Could use an update, version 2.0.4 available
- Fix build failure with pod2man 2.5+
- Bump PORTREVISION

While on it:
- Add NO_ARCH (port does not install arch dependent files)
- Clean up pkg-plis

The goal of this python library is to provide a way for python applications
to use Jabber/XMPP networks in a non-blocking way. This library is initialy a
fork of xmpppy one, but using non-blocking sockets.

- Update devel/libtool and devel/libltdl to version 2.4.2.418
- Patch libtool so it uses the same library version specification as on
  Darwin, Linux and other systems.  Given the version current:revision:age
  a library will be given the extension .so.major.age.revision with major
  equal to current-age.  Before libtool would use .so.current on FreeBSD.
- Patch libtoolize to remove two cases of umask 0 that caused libltdl
  files to be copied world writable (--ltdl option)
- Let USES=libtool patch this new version correctly
- Adjust all ports with USES=libtool:build and bump PORTREVISION on their
  dependent ports if a library version changed
