So I completely misunderstood, sorry. Because of this thread, I had another look at my port math/saga. And it came out, that I used LDFLAGS in a wrong context (graphics/opencv-core instead of graphics/opencv). So my problem with SAGA GIS and OpenCV should be solved. I will file a PR for this. Sorry for the noise.
