I believe this issue is not specific to libpostproc, but with
"libpostproc-dev and friends" the OP meant "library packages built
from libav sources" in general.

As Andres and others pointed out e.g. in
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=671302#35> libav has
several circular build-dependencies that give porters a hard time to
libav -> opencv -> libav
libav -> x264 -> libav
libav -> x264 -> gpac -> libav
Thorsten, that's three circular build-dependencies. Which one is the
fourth one that you mentioned in your report?
Anyway, all of these codecs are optional. So if you comment out the
B-Ds on libx264-dev, libopencv-dev and libcv-dev in debian/control and
remove the "--enable-libopencv" line in debian/confflags, libav should
build just fine and be available for bootstrapping of other packages.
