I've never found a likable version of BLAS/LAPACK, just versions I could
live with :-)

Hm - I see numpy on older OS - but not on M1. So Apple no longer bundles it?
And pip creates grief on NFS :(

Yes - this always bothered me...
But I don't think its always possible to automate it.
The likable version [.so] might not exist - only .so.ver might exist? [and it
might use blas but not lapack?]
Note: one way to avoid this issue is to let spack install
python,numpy,petsc,petsc4py

The chances of these problems are very slim because almost nobody builds Numpy
from source. I usually install it with pip. Pip-installed Numpy on Mac uses
Openblas, which is shipped together with the numpy wheels. The official API to
check which BLAS is used by Numpy is numpy.show_config().
