#58333: Error: Failed to build OpenBLAS (OS 10.14)
-----------------------------+----------------------
 Reporter:  meyerbe          |      Owner:  (none)
     Type:  defect           |     Status:  new
 Priority:  Normal           |  Milestone:
Component:  ports            |    Version:  2.5.4
 Keywords:  OpenBLAS, numpy  |       Port:  OpenBLAS
-----------------------------+----------------------
 I try to install python-packages that depend on OpenBLAS (numpy, netcdf4)
 and they fail when building OpenBLAS. I am aware that the problem has been
 raised before, but I wasn't able to follow the instructions to a
 successful result. Is it possible to give instructions that help someone
 like me who has no background in IT?

 I have tried to install both OpenBLAS @0.3.5_1 and OpenBLAS-devel
 @20190319 without success.

 Many thanks! Bettina
