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!
