title: Can't load batteries using FindLib in Ocaml TopLevel
body: <p>I successfully installed <code>ocaml-batteries-included</code> and <code>findlib</code>.</p>
  
  <p>I can do 'ocamlfind ocamlc -package batteries -c mycode.ml` without problems.</p>
  
  <p>Also, if I do <code>ocamlfind list</code>, I get</p>
  
  <pre><code>$ ocamlfind list
  batteries           (version: 2.0)
  batteries.pa_comprehension (version: 2.0)

  <p>The problem is <code>using batteries</code> in <code>ocaml (toplevel)</code>.</p>
  
  <p>I have set up <code>.ocamlinit</code> as told:</p>
  
  <pre><code>#use "topfind";;
  
  Toploop.use_silently
               Format.err_formatter (Filename.concat (Findlib.package_directory
               "batteries") "battop.ml");;
  </code></pre>
  
  <p>but when I launch <code>ocaml</code>, I get this:</p>
  
  <pre><code>$ ocaml
          OCaml version 4.00.1
  
  Findlib has been successfully loaded. Additional directives:
    #require "package";;      to load a package
    #list;;                   to list the available packages
    #camlp4o;;                to load camlp4 (standard syntax)
    #camlp4r;;                to load camlp4 (revised syntax)
    #predicates "p,q,...";;   to set these predicates
    Topfind.reset();;         to force that packages will be reloaded
    #thread;;                 to enable threads
  
  Exception: Fl_package_base.No_such_package ("batteries", "").
  </code></pre>
  
  <p>Further, if I do <code>#list</code> in <code>ocaml toplevel</code>, I get</p>
  
  <pre><code># #list;;

  camlp4              (version: [distributed with Ocaml])
