Hello,

I have been looking at several examples that use ocamlfind to
add a library to the ocamlbuild process. An example is:


let ocamlfind_query pkg =
  let cmd = Printf.sprintf "ocamlfind query %s" (Filename.quote pkg) in
  My_unix.run_and_open cmd (fun ic ->
    Log.dprintf 5 "Getting Ocaml directory from command %s" cmd;
    input_line ic)


However I get the following error:

Error: This expression has type string but an expression was expected of 
type
          'a -> 'b -> 'c


I am using version 3.11.2. Can anyone tell me what I'm making the error?

TIA,
Hugo F.
