pidgin-libnotify didn't have any recent release or commit so I developed a non-real-fork with more options: Pidgin-Libnotify+.
I packaged it in my overlay to properly test it, and I think it can be included in tree.
Here is the GitWeb of the directory with ebuilds.
I will maintain and improve this software at least for the time I'll use Pidgin.
I can maintain the ebuild too if it's needed.
This is a fork instead of a version bump, should be treated as a new package.
