you can expect to compile a lot of stuff since macosx is not supported
that good. which doesn't bother me. but a lot of packages are failing to
build on macosx so expect things to fail and fixing them manually (eg.
take patches from macports/homebrew and adjust nix expressions).

Shea Levy, started some work which might bring nix closer to macosx.
