- add various other missing WANTLIB (and LIB_DEPENDS in some cases)
- while there move PKGNAME=..pX to REVISION, and move some ports
to new-style LIB_DEPENDS
original diff from Brad, extensive checking by me (clean build of everything
related to liboil).
included, so the tools know that old ffmpeg versions won't satisfy the
dependencies listed in WANTLIB.
this way, attempting to install these packages with old ffmpeg will
no longer give you a cryptic error message as seen by dhill@.
