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
[email protected] 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.

Please report this bug at http://github.com/mxcl/homebrew/issues
It looks like an autotools configure failed.
Consider re-running the install with '-vd' to keep 'config.log' around:
    brew install -vd ffmpeg
Gist 'config.log' and any error output when reporting an issue.
Remember to include your config information: brew --config

Also try:
  `brew doctor` to check your setup for common problems.
  `brew missing` to check installed packages for missing deps.



$ brew doctor
Your OS X is ripe for brewing.
Any troubles you may be experiencing are likely purely psychosomatic.


$ brew missing
