  # Very Optional? Pulls in lots of dependencies but maybe not needed unless you're doing video analysis
  # Video analysis requires a bunch more things which we don't have: libgstreamer, libxine, unicap, libdc1394 2.x (or libdc1394 1.x + libraw1394).
  # We can leave this disabled for now.
  # Maybe we could add a flag?
  #depends_on 'ffmpeg'

  # There are other optional dependencies but they don't currently exist in Homebrew.

      return <<-EOS
  The OpenCV Python module will not work until you edit your PYTHONPATH like so:

    export PYTHONPATH="#{HOMEBREW_PREFIX}/lib/python2.6/site-packages/:$PYTHONPATH"

  To make this permanent, put it in your shell's profile (e.g. ~/.profile).
