189 If you think configure made a mistake, make sure you are using the latest
190 version from SVN. If the latest version fails, report the problem to the
191 ffmpeg-devel@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
193 if enabled logging; then
195 Include the log file "$logfile" produced by configure as this will help
