Error running setup.py on macOS about cymunk HOT 1 OPEN

I've also attempted the install command from the readme

python setup.py build_ext --compiler=mingw32 install

which results in a different error:

Reason: '/usr/local/opt/[email protected]/Frameworks/Python.framework/Versions/3.9/include/python3.9/pyconfig.h' does not mention '__GNUC__'.
