Or, build yourself:

nix-build -A ocamlPackages.mlgmpidl https://github.com/r-ryantm/nixpkgs/archive/3d02f2c2b68d50f556a1fd7f3ed80ae00bd35d8c.tar.gz

After you've downloaded or built it, look at the files and if there are any, run the binaries:

ls -la /nix/store/6y0gxl1rsl176p908dvp6d4yjs6wfqml-ocaml4.07.1-mlgmpidl-1.2.12
ls -la /nix/store/6y0gxl1rsl176p908dvp6d4yjs6wfqml-ocaml4.07.1-mlgmpidl-1.2.12/bin
