The attached patch switches to cython3-legacy as the short term workaround.

The package still fails to build due to test failures:

_ ERROR collecting 
.pybuild/test_python3.11/pymatgen/analysis/tests/test_chempot_diagram.py _
ImportError while importing test module 
'/build/pymatgen-2023.06.23+dfsg1/.pybuild/test_python3.11/pymatgen/analysis/tests/test_chempot_diagram.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
/usr/lib/python3.11/importlib/__init__.py:126: in import_module
     return _bootstrap._gcd_import(name[level:], package, level)

     from monty.string import unicode2str
E   ImportError: cannot import name 'unicode2str' from 'monty.string' 
(/usr/lib/python3/dist-packages/monty/string.py)

Kind Regards,
