Martin,

Yes, 0.9.8.4 fails to use the ocamlfind (even under USE_OCAMLFIND = 
true). This is fixed on SVN and the fix will be included in 0.9.8.5 
(which I am hoping to release tomorrow). Note that the -syntax is an 
ocamlfind's option, not ocamldep's.

If you want to include the fix manually, you can fix the OCamlScanner 
function definition (either by editing the OCaml.om, or by temporarily 
including it in your own OMakefile) to say:

public.OCamlScanner(src_file) =
     if $(OCAMLDEP_MODULES_ENABLED)
         value $(OCAMLFIND) $(OCAMLDEP_MODULES) $(LAZY_OCAMLFINDFLAGS) 
$(PREFIXED_OCAMLPACKS) $(OCAMLDEPFLAGS) -modules $(src_file) | 
ocamldep-postproc
     else
         value $(OCAMLFIND) $(OCAMLDEP) $(LAZY_OCAMLFINDFLAGS) 
$(PREFIXED_OCAMLPACKS) $(OCAMLDEPFLAGS) $(PREFIXED_OCAMLINCLUDES) 
$(src_file)

(here only the OCAMLDEP_MODULES line is different from the 0.9.8.4 version).
