Yeah.. For some reason it seems you have faad2 installed that's not in Portage anymore. Forcing a newer one in ffmpeg's ebuild now. 15 Dec 2008; <ssuominen@gentoo.org> ffmpeg-0.4.9_p20081014.ebuild: Change faad2 dep. to >= 2.6.1 wrt #251010.
i had media-libs/faad2-2.6.1-r2 installed, so this doesn't fix the problem.
re-emerging faad2 somehow did the trick. sry for the disturbance.
