This script that you link to doesn't mention x264 at all. Looks like it was updated and doesn't use x264 anymore. As for your ErrorMessage, I don't see that a "x264 1:0.svn20090829-0.0ubuntu1-1" package has ever existed. Did you compile this yourself and/or are you using any third-party repositories, packages, or PPAs?
