Meld 0.9.5 has been released. The existing ebuild works fine if you just change the name (good job!).
It would be nice if meld would depend on PyGtkSourceView as it adds syntax highlighting and line number support. http://sourceforge.net/projects/pygtksourceview
1.0.0 was released today. I will be adding this in tommorrow since they have moved to using pygtksourceview from gnome-python-extras. However, that ebuild attached to the bug needs some work, so hopefully by tomm night both will be committed.
gnome-python-extras went into portage yesterday, and the necessary keywording took place today / last night so no archs had to be dropped before committing meld 0.9.5. The reason its not 1.0.0 is because even though it "says" on the website its released, its not on the gnome ftp. I emailed the maintainer letting him know.
1.0.0 is up now...
okay, expect 1.0.0 soon.
fyi, i just committed 1.0.0, thanks for the reminder.
