>Description:
multimedia/ffmpeg depends on devel/pkgconf for build but does not list it as a build dependency. If ffmpeg's dependencies are changed to depend on devel/pkgconf only on build time it's possible that build of ffmpeg fails on configure stage because devel/pkgconf is not installed because ffmpeg does not pull it in.
>How-To-Repeat:

>Fix:
Use the new 'USE_PKGCONFIG=build' macro in the Makefile of multimedia/ffmpeg.
