Created attachment 243783 [details] rygel-0.6.0.ebuild
I'm picking this up because I've been actually working on this (but tracking 0.7, as 0.6 is ancient and does not support my TV set :( ). I got some sorta-working ebuilds, I'll see to push them out this weekend.
for the record, I have 0.7.8 in my dev overlay. (layman -a eva). Seems to work fine with gnome-2.30.
Pushed 0.8.2 and 0.9.1 (masked), slightly modified from Gilles' overlay.
