Pidgin has some deps too many and lacks others.
libIDN and especially orbit and gconf should be removed from the dependencies. gst-plugins-meta[v4l] is mandatory for video with farsight.
I'm currently trying to straighten this out, more info to follow.
gst-plugins-x264 should also be a dep for XMPP! Only then it works with, say, GTalk.
The gstreamer dependencies are, by the way, a pain in the back.
attach a diff to the current ebuild on top of your explanations, so devs can easily check on your proposal
Still waiting for more information from the reporter...
