http://www.afterstep.org/afterimage/getcode.php

Also I forgot to mention you need to install  http://ffmpeg.org/download.html

both of these are "./configure ; make; make install" packages and should install quickly and cleanly. Good luck otherwise.

python   ${PETSC_ARCH}/conf/reconfigure-${PETSC_ARCH}.py --with-afterimage

   It will use the old options plus anything new you add. It will only rebuild libraries that it has to rebuild.
