[Nix-dev] Override doesn't work as expected

[Peter Simons]

Hi,

I use the following override in ~/.nixpkgs/config.nix:

  packageOverrides = pkgs:
  {
    python = pkgs.python27Full;
    pythonBase = pkgs.python27Base;
    pythonFull = pkgs.python27Full;
    pythonPackages = pkgs.python27Packages;
  };

It appears that the xorg libraries depend on python26Base despite that
configuration, though. Is there an explanation why the override doesn't
seem to work for those libraries?

Take care,
Peter
