$NIXPKGS_CONFIG create some noise around reproducibility.  To ease
reproducibility, we have to keep it as pure as possible.  Thus we
should not depends on such environment variables.

Now NixOS allow you to define such configuration inside your computer
configuration by defining the option "nixpkgs.config".  So inside you
/etc/nixos/configuration.nix, just add:

nixpkgs.config = {
       git = { svnSupport = true; };
       subversion = { perlBindings = true; };
       wrapFirefox = { jrePlugin = true; };
};
