That seems to be a bug in libmpeg2, which seems to assume that darwin
implies PPC... You can try to make a bugreport to the libmpeg2 project.
A quick fix would be to disable cpu optimizations in libmpeg2 (if
possible), or not to compile libmpeg2 (ffmpeg can decode mpeg1/2 as
well).

There have been rerports of successive builts of VLC on a mac Intel.
