As Vladimir pointed out, your version of Nix is too old.  The easiest solution
is probably to install the latest version of Nix:

  http://hydra.nixos.org/job/nix/trunk/build.x86_64-linux/latest

E.g.

  $ nix-install-package --non-interactive --url \

http://hydra.nixos.org/build/5636025/nix/pkg/nix-1.6pre3181_8e74c0b-x86_64-linux.nixpkg

Hopefully nixos-rebuild will then work.  Afterwards you can do "nix-env -e nix".
