[Nix-dev] gcc for MacOS X

Hi Konrad,

I think I understand the problem you’re experiencing:

Can you remove GMP from /usr/local?

It’s generally a bad idea to have software available there on Hydra,
because then packages built with Nix may end up using them, leading to a
complete mess of impurity as the rest of the world knows it.  :-)

Note that you should soon be able to grab binaries from hydra.nixos.org.

HTH,
Ludo’.
