Describe the bug

The python statement import gpg fails with an ImportError or ModuleNotFoundError depending on python version and nixpgs channel.

Steps To Reproduce

I am building pkgs.python3.withPackages (p: [p.gpgme]) and then I execute python3 -c 'import gpg' from the result.

I do this for nixpkgs/nixos-24.05 and nixpkgs/nixos-unstable channel and for the python311 and the python312 derivation.

For example like this:

for nixpkgs in nixos-24.05 nixos-unstable; do
  for python in python311 python312; do
    echo Trying $python from $nixpkgs ...
    result=$(nix build -I nixpkgs=flake:nixpkgs/$nixpkgs --impure --print-out-paths \
      --expr '(import <nixpkgs> {}).'$python'.withPackages(p:[p.gpgme])')
    $result/bin/python3 -c 'import gpg'
  done
done

Results:

• nixos-24.05 with python3.11: ok
• nixos-24.05 with python3.12: ModuleNotFoundError: No module named 'imp'
• nixos-unstable with python3.11: ImportError: cannot import name 'gpgme' from partially initialized module 'gpg' (most likely due to a circular import) (/nix/store/y6xyvx9x542x2knw440ajblqy9922q3q-python3-3.11.10-env/lib/python3.11/site-packages/gpg/__init__.py)
• nixos-unstable with python3.12: ImportError: cannot import name 'gpgme' from partially initialized module 'gpg' (most likely due to a circular import) (/nix/store/ww0c5w89a905mzr45dqah77crc62rrsr-python3-3.12.7-env/lib/python3.12/site-packages/gpg/__init__.py)

Expected behavior

The module should be imported, no error message.

Additional context

On nixos-24.05 python3.11 is the default for the python3 derivation. On unstable it is 3.12.
