py-numpy: missed runtime dependency on macOS Monterey M1

[catap (Kirill A. Korinsky)]

When I install numpy it can't be used:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.9 from "/opt/local/bin/python3.9"
  * The NumPy version is: "1.21.3"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

I've seen this in a build log before too, and the fact that the problem seems to be that /opt/local/lib/libgcc/libgfortran.5.dylib cannot find /opt/local/lib/libgcc/libgcc_s.1.1.dylib makes it sound to me like a defect in the port that provides /opt/local/lib/libgcc/libgfortran.5.dylib, which on my High Sierra system at least is libgcc11, and we already know that does not build on Monterey (#63677, #63780) so I'm not sure how we even got to the point of py39-numpy being able to be installed.

[catap (Kirill A. Korinsky)]

The most wired things. When I rebuild it from scratch -s it works very well:

and removing or installing gcc-devel is enough to fix it.

[bal-agates]

See #63864 I just created. This suggests a quick fix that worked on my system. I am new to portfiles and it will take me some time to figure out if the problem can be fixed in the libgcc-devel portfile.

[catap (Kirill A. Korinsky)]

I'd love to confirm that #63864 fixed an issue.

[reneeotten (Renee Otten)]

so is this indeed fixed by the other ticket - if so, we should close this ticket

[michaelld (Michael Dickens)]

Guessing this issue was indeed fixed as noted. Closing.
