[CentOS] screwed up dependencies

Subsequent to trying to "yum update"-- it failed--, I tried to resolve the dependencies piecemeal:

# yum update faad2 .... --> Processing Dependency: libfaad.so.0 for package: ffmpeg ---> Package faad2.i386 0:2.7-1.el5.rf set to be updated --> Finished Dependency Resolution ffmpeg-0.5-2.el5.rf.i386 from installed has depsolving problems --> Missing Dependency: libfaad.so.0 is needed by package ffmpeg-0.5-2.el5.rf.i386 (installed) Error: Missing Dependency: libfaad.so.0 is needed by package ffmpeg-0.5-2.el5.rf.i386 (installed) ....

# rpm -q ffmpeg ffmpeg-0.5-2.el5.rf

Could it be that there's a packaging error in faad2 ?
