Locally, I am using the following to add it to defaultGemConfig for now (tested only on Linux).

      pkgs = nixpkgs.legacyPackages.${system};
      gems = pkgs.bundlerEnv.override
          {
            inherit bundler;
          }
          {
            inherit ruby;
            name = "my-app";
            gemdir = ./.;
            gemConfig = pkgs.defaultGemConfig // {
              fast_excel = attrs: {
                buildInputs = [ pkgs.zlib ];
              };
            };
          };
