@rick.torzynski, thanks for venturing into the great virtual (env) unknown. I am not that courageous, so I am planning to install non virtual with a backup of my card prior to the installation.
I have been using OpenCV 2.4.9 on a desktop RaspberryPi for some time, but am planning to take whatever: “sudo pip install opencv-contrib-python” will install.
(Trying to shrink my 16GB backup so I can verify it with a 15.9GB card at the moment.)
Looking forward to hearing about your success,
Alan (otherwise known as CyclicalObsessive)
