Bug 285467: x11-toolkits/gtk40: ModuleNotFoundError: No module named
'distutils.msvccompiler'
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285467



--- Description ---
When used with (experimental) update of prerequisite port devel/py-setuptools
(> 63.X, I used 64.0, 75.3.0 and 75.8.2), some FreeBSD ports relying on
devel/py-setuptools seemingly bail out with a strange error referring to a more
Microsoft related compile(?):

[...]
Traceback (most recent call last):
  File "/usr/local/bin/g-ir-scanner", line 103, in <module>
    from giscanner.scannermain import scanner_main
  File "/usr/local/lib/gobject-introspection/giscanner/scannermain.py", line
35, in <module>
    from giscanner.ast import Include, Namespace
  File "/usr/local/lib/gobject-introspection/giscanner/ast.py", line 29, in

    from .sourcescanner import CTYPE_TYPEDEF, CSYMBOL_TYPE_TYPEDEF

    from distutils.msvccompiler import MSVCCompiler
ModuleNotFoundError: No module named 'distutils.msvccompiler'

Also, such an error occurs with several other ports relying on
devel/py-setuptools, like

math/py-numpy
