your snippets look ok. there must be something you're missing.

does you system nvim point to /nix/store/...-neovim-2015-06-09-configured?

what i do in my configuration:

    nixpkgs.config.packageOverrides = pkgs: {
      neovim = pkgs.neovim.override {...};
    };
    environment.systemPackages = with pkgs; {
      neovim
      ...
    };

that works for me.
