 I am able to build py36-numpy on a 10.11 system with the variant +gcc9
 +openblas. Perhaps you should check your installation of the few ports
 that numpy depends on for building or running. In particular, you should
 check your variant on fftw-3. Of course, you may find you can upgrade it
 without doing any of that. I have discovered that +clang37 is not
 necessary in an absolute sense, and I think that is a good thing.
