To avoid cluttering of systems, the Gnome team introduced split gnome-python bindings. Please update the dependencies of revelation accordingly. At least dev-python/libgnome-python dev-python/gconf-python are needed.
Created attachment 179320 [details, diff] Patch to Revelation 0.4.11-r1 This is a patch to the current ebuild which replaces the gnome-python meta-dependency with explicit dependencies on the necessary split packages. Also this introduces a new patch which removes the need for the gnome-python-extras package, as this is bogus nowadays. (The check comes from times when the panelapplet-stuff was still in gnome-python-extras, which is ancient history now ;) ).

Ah, I was hoping someone would do the work for me. Thanks for the patch!
