 Building mpeg2vidcodec fails to find the libXext library with the
 following error:
 "ld: library not found for -lXext"

 Looking through the recent commits, I noticed that revision r47564 altered
 the included libraries.[[BR]]
 Moving aside "/opt/local/lib/pkgconfig/x11.pc" allowed the build to
 correctly add the included libraries and build.[[BR]]
 Perhaps this is really a bug with pkgconfig or an issue with my
 installation?

 Below is the log from the failed build.
