Hey,
I'm using OCamlMakefile for a project that uses lwt, and I'm having  
trouble getting the right combination of settings to use the syntax  
extensiosn, specifically it is failing trying to calculate dependencies:

ocamlfind ocamldep -pp "camlp4o pa_lwt.cmo " pm_sge_utils.ml > ._d/ 
pm_sge_utils.d
Camlp4: Uncaught exception: DynLoader.Error ("pa_lwt.cmo", "file not  
found in path")


What do I need to do?

Thanks!
