Huh? FFmpeg already works without memalign. And there is even a hack
that allows even the assembler optimizations to work without it.
So to me it seems your example actually confirms Mans' opinion?
Also I think there is no problem to _also_ try pkg-config, but depending
on it really is not a great thing - also as it encourages projects using
pkg-config to do sloppy dependency-managment.
And for what it's worth, libdirac/schrodinger to me are the typical
examples that really have no reason at all to _need_ pkg-config.
