I believe this has already been fixed upstream. I encountered it and grabbed a newer snapshot as a result.
Created attachment 122811 [details] ebuild patched for exit_is_forbidden() Latest stable ebuild patched to avoid this problem as suggested in http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-March/026391.html
I can confirm the attached ebuild solved the original problem
should be fixed in current versions
