Thanks for your quick reply, Alan. I adapted the line
sudo ln /usr/local/lib/ocaml/libcamlstr.a /usr/local/lib/ocaml/libstr.a
to
sudo ln /opt/local/lib/ocaml/libcamlstr.a /opt/local/lib/ocaml/libstr.a
in order to reflect MacPorts' location.

Now I'm getting another error message:

Do I need a different OCaml build?
