Bug#1033353: libpwquality failing to build on bookworm with python 3.11

[Mayer, Dirk]

Source: libpwquality
Version: 1.4.5-1
Tags: bookworm ftbfs

When I build this package from source, the build fails. Please see log output at the end.
My build environment is a container image based on Debian testing bookworm, which already includes python3.11

After some research I guess it may be related to the upgrade to pyhton3.11 and the new behavior which enforces pip install packages only in venv.
There is also a separation of user und system packages which may be the problem in an isolated buildroot.
There maybe a new PEP668 involved: https://peps.python.org/pep-0668/
https://peps.python.org/pep-0668/#keep-the-marker-file-in-container-images
https://discuss.python.org/t/python3-m-pip-install-user-broken-in-debian-testing/24268
And a long discussion about distros:

bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not
on PYTHONPATH and which Python does not read ".pth" files from.  The
installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /work/tmp/libpwquality_1.4.5-1/libpwquality-1.4.5/debian/tmp/usr/local/lib/python3.11/dist-packages/

and your PYTHONPATH environment variable currently contains:

    ''

Here are some of your options for correcting the problem:

* You can choose a different installation directory, i.e., one that is
  on PYTHONPATH or supports .pth files

* You can add the installation directory to the PYTHONPATH environment
  variable.  (It must then also be on PYTHONPATH whenever you run
  Python and want to use the package(s) you are installing.)

* You can set up the installation directory to support ".pth" files by
  using one of the approaches described here:

Please make the appropriate changes for your system and try again.

By the way: 
There are multiple other python based source packages, which are also failing to build in a bookworm based build environment, all with a similar error message:
dh_install: warning: Cannot find (any matches for) "usr/lib/python3*" (tried in ., debian/tmp)
dh_install: warning: python3-pwquality missing files: usr/lib/python3*

These are: libprelude_5.2.0-5, libseccomp_2.5.4-1
