ocamlduce: build fails due to warnings turned into errors

[ludwig@…]

My attempts to install ocamlduce 3.08.4pl3, Revision 1 failed because the build encountered warnings about unused variables and ocamlc.opt was passed the option -warn-error. This is on an Intel MacBook Pro with OS X 10.4.11.

The following ports are currently installed:
  ocaml @3.10.0_0 (active)
