Comment (by Gandoon):

 Replying to [comment:3 Dave-Allured]:
 > Eric, just for my information, did you try either `lapack` or `lapack
 +gfortran`, without either `+accelerate` or `+openblas`?

 No, I did not. I have always had the `+openblas` enabled. It has never
 given me any trouble in the past. I could as an experiment try to build it
 without blas, but I am unsure if the rest of my system will work as
 intended in that case. I will return with the results once it has been
 tried.

 As for the `-v`option mentioned, I always use it. Plus, as Joshua
 mentioned, it doesn't matter for the logs anyway. I am unsure of there is
 any `-vv` or similar option that gives extra verbose information that
 propagate to the build system and logs. But if there is, I have not used
 it.
