That was what I needed. I had looked at wrapPythonProgram beforem, which didn't work, because these programs are actually bash scripts, that call the python interpreter.

Now, I added `makeWrapper` to `buildInputs`, and added

    postFixup = ''
      for i in "$out/bin/"*; do
        wrapProgram "$i" --prefix PYTHONPATH ":" "$PYTHONPATH"
      done
    '';

to my derivation and everything works.

Thanks a lot.
