I'm trying to figure out how to use the Camlp4MacroParser extension
but I can't seem to find the Loc module it requires:

macro.ml:
"""
open Camlp4.Sig
let here = __LOCATION__
"""

Build command:
ocamlc -I +camlp4 -pp "camlp4o -parser Camlp4MacroParser"
camlp4lib.cma -o macro macro.ml

Result:
File "macro.ml", line 2, characters 11-23:
Unbound value Loc.of_tuple

According to the documentation the Loc module's supposed to be in
Camlp4.Sig.  Any clues?

Thanks,
