py39-numpy @1.20.3_0+gfortran+openblas fails to build py39-pyerfa (M1 Big Sur)

[Schamschula (Marius Schamschula)]

While building py39-pyerfa only M1 mini, I get the following error:

:info:build running build_ext
:info:build Traceback (most recent call last):
:info:build   File "/opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/numpy/core/__init__.py", line 22, in <module>

This means there is something wrong with the +gfortran variant of py-numpy. This is a similar situation as in ​https://trac.macports.org/ticket/62874 (octave).

I currently have OpenBLAS @0.3.15_1+gcc10+lapack+native active. I can't install OpenBLAS @0.3.15_1+gcc11+lapack+native. Also see: ​https://trac.macports.org/ticket/62727

Unfortunately, py39-numpy +gcc10+openblas also fails to build.

is this still an issue or has this been resolved by now?

py39-pyerfa has since installed cleanly.
