Mac OS X textmate running OCaml code prompt error uncaught exception:invalid_argument ("Fl_package_base.query")
Workaround, modify the ~/library/application\ support/textmate/managed/bundles/ocaml.tmbundle/support/ocamlmate/run_script.rb file

@ocamlc = argv[0] #修改为: @ocamlc = File.basename (argv[0])

Get.

By the way, beautify the output, eventually modify the file:
