Bug#404395: libcamlimages-ocaml-dev: Fails to load images.

Hello,

In gmane.linux.debian.devel.ocaml, you wrote:

You should use OImages in place of OImage.

Really, you should use :
ocamlfind -package camlimages -linkpkg -o load_image load_image.ml

But anyway, take a look at your command line. You don't load anything
dealing with png or jpeg... It should have made you think there was a
problem.

Using ocamlfind, load everything, and seems to work as expected.

Well, in fact, i need to do some patching in my META.camlimages to made
this example work, i open a bug with the good META.camlimages.
