python 3.7 problems

[Thomas Klausner <wiz%netbsd.org@localhost>]

So a recent update of py-setuptools_scm introduced a cyclic dependency
for python 3.7 because it needs the importlib-metadata module, but
that needs py-setuptools_scm to build.

The missing dependency now leads to heavy fallout for python 3.7 modules, a sample:

http://www.ki.nu/pkgsrc/reports/current/NetBSD-9.0/20221023.0731/py37-execnet-1.9.0nb1/build.log

Is someone willing to fight the windmills and get one of the upstreams
to fix the cycle?

Or should we just give up on python 3.7? The official EOL is
2023-06-27 but we already have some packages in pkgsrc that do not
support this version any longer.

Other suggestions?
 Thomas

Log Message:
py-setuptools_scam: comment out py-importlib-metadata dependency

This is required per setup.cfg for python < 3.8, but this introduces
a cyclic dependency.

To do: mark this (and everything using it) as not for python 3.7, since
it probably won't work correctly?
