ffmpeg/x264/gpc circular dep loop

Folks, I am running F20 PPC64 on a Mac G5. I have been able to download the source RPM's from RPM Fusion and do an rpmbuild --rebuild on most of my needed packages. However, I am running into an issue with these three packages. I download the ffmpeg srpm, and it says that I need gpac, and x264. However, when I download the x264 or gpac srpm and try to compile it, it says that I need ffmpeg. This is worse than dll hell! Is there a manual/instructions on getting around this circular logic. I am stuck in a catch-22. Thanks in advance, Emilio
