As of bug 140498 xzgv has been removed from the portage tree as it was an old unmaintained software, but now it seems that there is a new mantainer upstream: http://sourceforge.net/projects/xzgv/ xzgv-0.9 is out with GTK2 and imlib2 support. It could be added into the tree again?
Created attachment 134022 [details] Proposed skel ebuild I am attaching a possible base ebuild for the xzgv-0.9 package. The xzgv documentation says that it depends on >=GTK+-1.2 and >=imlib-1.0, but the "NEWS" files says that imlib1 is no longer supported and that xzgv-0.9 uses GTK+-2 (a quick ldd check seems to confirm that it's linked with the gtk-2 libs).
I've added it, thanks for initial ebuild.
