Kino tried to emerge itself using the existing ffmpeg on my system (yes, I hadn't done an update world first). It choked on a missing field in a struct that has since been added, at least as of ffmpeg-0.4.9_p20051216. If the USE flag for ffmpeg is set, the ffmpeg requirement should be >= 0.4.9_p20051216.
There's no lower version in portage. How about updating your system properly (emerge -uD world)? ;)
