hi Nick,

I believe that that indicates that the OpenCV libs don't know their
own full names, usually because install_name_tool wasn't invoked.  The
OpenCV folks have reportedly fixed this on trunk of OpenCV (e.g.,
https://code.ros.org/trac/opencv/changeset/3298).  We should probably
pull the necessary fix(es) into cturtle/vision_opencv.
