-------------------------+-----------------------------------
 Reporter:  ATL-Flaneur  |      Owner:  seanfarley, michaelld
     Type:  defect       |     Status:  assigned
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.5.4
 Keywords:  SciPy        |       Port:  py37-scipy
-------------------------+-----------------------------------
 I'm on MacOS 10.14.2 (18C54) and after first running into this problem did

 Then:
