math/py-numpy + MacOS 11.1 / Darwin 20.2.0

[Brook Milligan <brook%nmsu.edu@localhost>]

I had to use gcc10 to compile math/py-numpy on a MacOS 11.1 / Darwin 20.2.0 machine.  None of gcc7, gcc8, or gcc9 worked; they all failed to find an appropriate fortran.

I forced gcc10 by setting GFORTRAN_VERSION=10 in mk.conf, but presumably this should be encoded in the package Makefile.

Should this be done with GCC_REQD=10 conditional on the Darwin version?  Is there a better idea?

Thanks for your help.

Cheers,
Brook
