unknown option `-package'

Hi there, I tried to use the ocaml bundle and it doesn't work as is.
First I had to install ocamlfind (well opam and then ocamlfind) but now I have this problem :

ocamlfind /opt/local/bin/ocamlc -o /var/folders/p7/c63kqjrx32n8882cpl90s1bw0000gn/T//ocaml1tP7y7 -I /opt/local/lib/ocaml/threads -package '' -linkpkg str.cma unix.cma threads.cma /var/folders/p7/c63kqjrx32n8882cpl90s1bw0000gn/T//ocamlVvlmuM.ml 2>&1
/opt/local/bin/ocamlc: unknown option `-package'.

I guess this is an issue with the compilation script. I checked my ocaml installation and it's seems fine (I tried with the official binary realease and the macports version.)
