I'm getting an error when trying to build the program on macOS 12.6 as per the instructions https://github.com/jappeace/cut-the-crap#from-source

~/Syncthing/git/cut-the-crap% nix-build . --show-trace

             |                                  ^
          193|         } // (lib.optionalAttrs (stdenv.hostPlatform != stdenv.buildPlatform && !dontAddHostSuffix && (attrs ? name || (attrs ? pname && attrs ? version)))) {
