How you did to install OpenCV 3.1? I'm using OpenCV 3.1 but I installed 
using a patch from here 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=210505
To use others ports that needs OpenCV I compiled from sources using 
ports collection. For example, ffmpeg needs OpenCV so, I deinstall 
ffmpeg and OpenCV 2.4, install OpenCV 3.1 and rebuild/install ffmpeg 
from ports.
