Seems it is a required dependency for: farstream which is a dependency of both pidgin (via the "gstreamer" USE flag) and telepathy-qt

monty ~ # emerge -av pidginThese are the packages that would be merged, in order:Calculating dependencies... done!emerge: there are no ebuilds to satisfy "media-plugins/gst-plugins-libnice:1.0".
(dependency required by "net-libs/farstream-0.2.8-r1::media-kit" [ebuild])
(dependency required by "net-im/pidgin-2.13.0-r1::net-kit[gstreamer]" [ebuild])
(dependency required by "pidgin" [argument])

Is this an ebuild we can sync from gentoo-staging?
