I was working to install OpenCV to work with Python on my Mac http://www.jeffreythompson.org/blog/2013/08/22/update-installing-opencv-on-mac-mountain-lion/
I got everything installed without problems, but by the end I got this wired problem mentioning that the "OpenCV library" is not connected
$ pkg-config --cflags opencv
-I/usr/local/include/opencv -I/usr/local/include
$ brew install opencv
Warning: opencv-2.4.6.1 already installed, it's just not linked
$ python
Python 2.7.3 (v2.7.3:70274d53c1dd, Apr 9 2012, 20:52:43)
