Just a note: mencoder does not only look for x264 libs. It also
*needs* x264 headers to actually add support for it. When you install
from source, headers are also installed. Some distros, however, split
x264 into two packages; one that provides just the libs and one that
provides the devel stuff (like headers and so). This may also have
been a problem for you but I'm unsure (can't really tell from here
what's going on on your system)
