This is not a very helpful log, I hope it gives more information earlier
or later? If not, we'll have to teach its build system to show the actual
test output somewhere.

I would guess that the problem is that it still uses python3-distutils
(that's being worked on upstream, but slower than I would like), but even
though that package Provides python3.12-distutils, it doesn't contain
an implementation.

Depending on python3-setuptools | python3 (<< 3.12) would maybe work?

Thanks, I had been wondering how maintainers of packages that use a single
Python version were meant to test this!
