I haven't yet got around to trying this installer out, though I think it is being actively maintained.

If correctly configured, you shouldn't need to do this - OCaml itself should know it. I believe that OASIS compiles .c files the "correct" way (i.e. using ocamlopt which itself calls the correct gcc).

I don't think it's related, but I use the following patch for Cryptokit (based on info from Sylvain):

}
But that's simply to pass a link directory for zlib. With that patch, I have no problems running:
ocaml setup.ml -configure --enable-zlib
ocaml setup.ml -build
ocaml setup.ml -doc
ocaml setup.ml -install
And it does seem to work.
HTH,
David
