This package failed build from source when test-built against a version of
dh-python without a python3-setuptools dependency.

distutils is no longer part of the Python standard library, since 3.12. But a
minimal version of it becomes available when the python3-setuptools package is
installed.

Please add a Build-Depends on python3-setuptools to your package, or migrate
the package's build system away from setuptools/distutils.

If you run into any difficulties, please raise them on
debian-python@lists.debian.org.

This bug has been filed at "important" severity, as the change hasn't been
made in dh-python yet, but this may be raised to RC before the trixie release.

Thanks,

Stefano
