Comment (by mf2k):

 I am not able to get a working py37-scipy. It keep trying to rebuild and
 fails after 3 attempts. I'm not sure if this is related to this issue or
 not? Here are my relevant  installed ports.
 {{{
 $ port installed OpenBLAS-devel ld64 cctools py37-numpy py37-scipy
 The following ports are currently installed:
   cctools @921_1+llvm70 (active)
   ld64 @3_1+ld64_xcode (active)
   OpenBLAS-devel @20190210_0+gcc8+lapack (active)
   py37-numpy @1.16.1_0+gcc8+openblas (active)
   py37-scipy @1.2.1_0+gcc8+openblas (active)
 }}}

 I have tried various combinations with no success. Can anyone share a
 working combo?
