Bug 947690 – sys-apps/portage-3.0.66.1-r1 - emerge throws an ".../threading.py", line 1383, in __del__ TypeError: 'NoneType' object does not support the context manager protocol" since upgraded to python 3.13

emerge --info

Since I enabled python on my ppc/23.0/musl system via PYTHON_TARGETS="python3_12 python3_13" in make.conf and did an 'emerge -uND world' I get this error every time I invoke emerge:

 # emerge -p1v python

These are the packages that would be merged, in order:

So far I am only seeing this on my ppc system, not on ppc64 or amd64.

At emerging stuff I get runtime errors like this:

In #gentoo-powerpc IRC Sam pointed me to a forum post with the same error message: https://forums.gentoo.org/viewtopic-t-1172337.html

The linked build.log (https://bpa.st/GEXQ) shows the same error message on a x86_32/musl system using python-3.13.

This looks like more of a python problem than a portage problem.
