What I've done to make it work:

autoreconf &&
CPPFLAGS+=' -I /usr/include/python3.13' \
./configure --prefix=/usr    \
            --disable-static \
            --with-default-dict=/usr/lib/cracklib/pw_dict &&
sed 's/makeSuite/TestLoader().loadTestsFromTestCase/' \
    -i ./python/test_cracklib.py
make &&
make install

I.e. "autoreconf" makes it to recognize python3.13 as an interpreter,
and CPPFLAGS makes it able to find pyatomic_gcc.h.  The sed adapts the
test suite for Python 3.13.

Then `python3 -c 'import cracklib; cracklib.test()'` for testing the
python module.
