Ok, noted.

I think that should be:

    ocamlfind ocamlopt -package camlimages -linkpkg -o load_image load_image.ml

but that still fails with:

    No implementations provided for the following modules:
      Graphics referenced from /usr/lib/ocaml/3.09.2/camlimages/ci_graphics.cmxa(Graphic_image)

However, using ocamlc

    ocamlfind ocamlc -package camlimages -linkpkg -o load_image load_image.ml

works. Why?

Actually no. I expected that linking camlimages.cmx would link everything
I needed. Most other Ocaml libraries work this way (unix.cmxa, str.cmxa,
lablgtk, lablgl and so on).

Is that why the "ocamlfind ocamlopt" line above doesn't work?
