If I remember well, the ELF format used by Linux tools allow to link
.so files with other .so files. So, libavcodec.so is linked with
libavutil.so during ffmpeg build, and you do not need to explicitly
link libavutil.so.
Maybe OS X tools do not allow similar tricks, or you are linking static
libraries on OS X?
