X-Spam: no; 0.00; -pp:01 -pp:01 ocaml:01 foobar:01 usr:01 ocamldep:01 foobar:01 pcre:01 netstring:01 camlp:01 lib:01 cmo:01 lib:01 sexp:01 cmo:01 

Oops, I meant also to add, it does not matter if it is a -pp option, for 
examlpe if I have

flag ["ocaml"] (A "foobar");;

then I get

$ ./make.sh
+ /usr/local/home/godi310/godi/bin/ocamldep.opt foobar -pp foobar 
-modules live_query.ml > live_query.ml.depends
sh: foobar: command not found

Thanks!
