[Debian-pan-maintainers] Bug#1056042: xrayutilities ftbfs with Python 3.12

[s3v]

Dear Maintainer,

After uncertainties/3.1.7 entered in unstable, your package builds fine
in my sid chroot environment and all tests pass.

Import that triggers the failure:

  from past.builtins import basestring

was turned in:

if sys.version_info < (3,):
     from past.builtins import basestring
else:
     # Avoid importing from past in Python 3 since it utilizes the builtin
     # 'imp' module, which is deprecated as of Python 3.4, see
     # https://docs.python.org/3/library/imp.html. The 2to3 tool replaces
     # basestring with str, so that's what we effectively do here as well:
     basestring = str


Kind Regards
