I am one of those guys who had some trouble with disfunctional opencv libs, but did not react. Sorry for that, I had been very busy last months. math/saga is a GIS application, which uses OpenCV in one of its modules. For some month now, SAGA GIS disables this module at start time of the program. I tried your patch for graphics/opencv, but nothing changed for me. It seems, the opencv libs continue to be non usable. > Note: you need to import numpy before cv2. Does this mean, we have to rebuild and reinstall math/py-numpy before installing graphics/opencv? Do we have to also reinstall graphics/opencv-core?
