Seems like /usr/ports/UPDATING had been abandoned. The last update was over
a year ago. This SHOULD have been in UPDATING.

If I remember correctly, the fix is to de-install both py38-packaging and
py38-setuptools.

This assumes the use of portmaster, but it should work with whichever tool
you use.

The problem was that a function was moved between ports and, as a result,
you can't build either port when the old version of either is installed.
