I updated the kopete-0.12-alpha1 ebuild to add jingle support (and the related dependencies). I then wrote a patch to make it compile properly with --enable-jingle (changed an include path). I modified the net-im/kopete ebuild for this.

This is a WONTFIX for now. The reason is that it requires an oRTP version that is not the last one and it's not SLOTed, and as portage can't handle those dependencies correctly, I'd rather wait to see if next versions will be updated to use newer versions of oRTP.
