At this step, OpenCV should have been installed in/usr/local/lib/python2.7/site-packages.
However, to use OpenCV in the cv virtual environment, we first need to match the link to our site-packages directory:
$ cd ~/.virtualenvs/cv/lib/python2.7/site-packages/$ ln -s /usr/local/lib/python2.7/site-packages/cv2.so cv2.so$ ln -s /usr/local/lib
