gpa version 0.7.3 has been out for a while. I'll attach an ebuild (well, a diff actually) that works for me. But it needs a little work regarding the pixmaps and the .desktop file, and I don't know how to do that right.
Created attachment 85894 [details, diff] diff from ebuild version 0.7.0-r2 to 0.7.3
Thanks, I bumped gpa in cvs. I didn't have a look at the pixmaps/desktop file issue, so I am leaving this bug open.
I just took care of the pixmap and .desktop issue.
