Yeah, this is not very cool.  I've just asked a question about why
this package is still stuck after 3 days ...

Answer is yes ... for some packages.

When I published the second set of OCaml packaging guidelines[1] I
made the use of a META file for findlib mandatory.  So all new library
packages should be findlib compatible, and 'ocamlfind -package ...'
should just work.  This is also in alignment with Debian's packaging
policy.

However there are still some old packages which don't conform to this
guideline, and it seems like ocaml-camlimages is one of those.  I've
just filed a bug[2].  If you find any other packages like this, please
also file bugs and assign them to me.

This shouldn't stop you from using the package though.  You can just
compile it like this:

 ocamlfind ocamlc -package any,other,pkgs -I +camlimages foo.ml
 ocamlfind ocamlc -package any,other,pkgs -linkpkg -I +camlimages \
   ci_core.cma foo.cmo

It's a lot easier with proper findlib support though :-)

I'm afraid I don't know very much about omake, but I'm sure a command
such as the above would work.

Rich.
