#66304: py-setuptools 65.6.0_0 breaks py-numpy builds

-----------------------+------------------------
 setuptools 65.6.0 changes the log API such that all NumPy builds from
 source fail (the code causing the error predates the earliest version of
 NumPy used in MacPorts right now [1.16]). While this -is- a NumPy problem
 from a certain perspective, we need to fixup -all- NumPy uses of log to
 work again; luckily all of the NumPy code looks the be virtually
 identical. I hope this (ab)use of the log API is limited to NumPy!

 Here's the NumPy code that fails:
 https://github.com/numpy/numpy/blob/maintenance/1.23.x/numpy/distutils/log.py#L4

 Here's the setuptools change that causes the issue:
 https://github.com/pypa/setuptools/commit/9b8a6ef60b2b490bcf60b9dd7f0d43d46f49e489
 #diff-f4970eee1e6aebcf5dd5528890fbf7ddce06a8929dd9649b16b94f04277eb85b

 Here's an older version of the setuptools code that works:
 https://github.com/pypa/setuptools/blob/bb9fb1fcfe37c1ef1e29e1e6d1fc4e483c743380/setuptools/_distutils/log.py
 . Note the `class Log` that is required by NumPy, which was removed for
 this latest release.

 Here is the NumPy issue: https://github.com/numpy/numpy/issues/22623 .
 NumPy folks say to not use this setuptools, and they won't be fixing the
 issue; if someone wants to fix it & it doesn't break anything, they will
 consider merging it.
