286 If you think configure made a mistake, make sure you are using the latest
287 version from Git. If the latest version fails, report the problem to the
288 ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
290 if disabled logging; then

293 include the log this produces with your report.
