Current state

Buggy output:

$ clang2py --version                                                    
versions - clang2py:Please install the latest version of this python package python-clang:21.1.7 clang:21.1.8 clang_filename:libclang-21.so.21 

On Ubuntu 22.04, with libclang-21-dev system package installed.
Python 3.12, with packages: clang==21.1.7, ctypeslib2==2.4.0

Proposed fix

On commit 9a352bd, tag v2.4.0
