[Nix-dev] gcc has stopped working on Mac OS X Mavericks

[Alfredo Di Napoli]

Hello nixers,

I think I'm having a very similar problem here which I do not have enough
nix knowledge to debug. I have reinstalled nix-1.7 doing this (as suggested
from the nix website):

 curl https://nixos.org/nix/install | sh


So far so good. But when I try to install ANYTHING, (e.g. "hello"), this is
what I get:

installing `hello-2.9'
these derivations will be built:
  /nix/store/al6xyibqncn9aicmkffr0n90xgxnfrm4-hello-2.9.drv

-- Which makes me suspect the error is very similar. Likewise, my xcrun
thinks I'm on 10.10.
I have seen mentioned as workaround to export that environment variable
inside  pkgs/stdenv/nix/default.nix: I have tried both "extraCmd" and
"shellHooks" inside "stdenvNix", but with no luck. My nix-expression
knowledge stops here unfortunately :(

Any kind soul keen on helping?
Thanks!
Alfredo
