[Nix-dev] Python: Provide your own buildPhase and installPhase.

[Freddy Rietdijk]

Hi,

What are you trying to achieve? You want to package panda3d?

The `buildPythonPackage` function builds by default setuptools/distutils
Python packages. When passed `format="flit"` it builds from Flit source,
and when passed `format="wheel'` it takes the wheel and installs it. The
fourth option is, as you mentioned, `format="other"`. In this case, it uses
the `buildPhase` and `installPhase` from `stdenv.mkDerivation` and is
therefore useful for when a Makefile is provided and the package has
scripts that need to be wrapped or provides Python modules.

An example of `format="other"` is how we provide the `tkinter` module from
the standard library.
You don't have to copy the code of the `buildPythonPackage` function, just
call it and pass in the arguments.

Freddy
