[Nix-dev] PYTHONPATH and eggs

[Mathijs Kwik]

Hi Florian,

I used "buildPythonPackage" for the 2 modules (xattr and acl).
Bup itself is not a python package by itself (I think), so I gave that
a normal package, and just wrapped the (only) binary with PYTHONPATH
prefixes, as I've seen in other packages in the nixpkgs too.

Please have a look here:
https://github.com/bluescreen303/nixpkgs/commit/4426f0a2c62d42f63cc57e86e80f38b15ac85250

To test if it works, you can type "bup meta". That will now warn about
the missing libraries.

Thanks for your help,
Mathijs
