 While working with opencv, I realized that under mac os x there is a
 serious bug in VideoCapture that prevents capture from webcams.  Details
 can be found [https://code.ros.org/trac/opencv/changeset/3018#file2 here]
 and [http://permalink.gmane.org/gmane.comp.lib.opencv.user/212 here].

 As noted in the first link there is a patch for it in SVN, which I've
 backported to the macports 2.1 version.  Attached are the diff for the
 Portfile and the diff for the offending source file in opencv.

 Theoretically OpenCV 2.1.1 will be out soon and it should fix this
 problem, so it may not be worth committing this port, but I wanted it out
 there.
