Comment (by detlevd):

 René - thanks for the patch!
 I applied it to the opencv Portfile and performed an upgrade --force on
 opencv.
 Everything works as expected now. No more dependecies on python35 in
 variant +python34.
 Scripts using 'import cv2' now work as before. I did not check it for
 +python35 though.
