root@server [/usr/local/src/ffmpeg]# ./configure --prefix=/usr/local/bin --enable-mp3lame --enable-x264 --enable-gpl
ERROR: x264 not found
If you think configure made a mistake, make sure you are using the latest
version from SVN.  If the latest version fails, report the problem to the
ffmpeg-devel@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.err" produced by configure as this will help
solving the problem.
