Comment (by barracuda156):

 Replying to [comment:1 ryandesign]:
 > It's not immediately clear to me what the problem would be. ffmpeg does
 depend on pkgconfig and zvbi. zvbi does install zvbi-0.2.pc. Please attach
 the config.log.

 Ah, I guess this: #64212

 Why does it have to be _not_ disabled for any platform? MacPorts avoids
 rpaths, AFAIK, and they are known not to work correctly on numerous
 instances.
