title: Installed ocamlfind (findlib), but never can find any extra package in Mac
body: <p>Just got a new Mac, Mountain Lion and I wish to make all ocaml related stuff set up.</p>
  
  <p>I used the following commands:</p>
  
  <pre><code>opam switch 4.00.1
  
  opam install findlib
  
  opam install batteries
  </code></pre>
  
  <p>All are installed successfully without errors.</p>
  
  <p><strong>But I can't use <code>batteries</code>, <code>bisect</code>, etc. Always say <code>package can't be found</code>.</strong></p>
  
  <p><strong>Any idea?</strong></p>
  
  <p>Should I set any <code>path</code> or something?</p>

  <p>For more information, I followed these steps:</p>
  
  <pre><code>1. install homebrew
  
      http://mxcl.github.com/homebrew/
  
      ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
  
  2. Emacs for Mac OS X
  
      http://emacsformacosx.com/
  
  3. Install tuareg-mode
  
      http://forge.ocamlcore.org/forum/forum.php?forum_id=808
  
      http://marmalade-repo.org/
      Add to your .emacs: (require 'package) (in home directory)
  
      (add-to-list 'package-archives 
          '("marmalade" .
            "http://marmalade-repo.org/packages/"))
      (package-initialize)
  
      M-x eval-buffer to evaluate it, and then do M-x package-refresh-contents to load in the package listing.\
  
      ** m-x list-packages **
  
      select tuareg package
  
      click install
  
  4. Install OCaml, OPam, rlwrap
  
      make sure XCode command line tool is installed:

      brew install ocaml
  
      brew install opam
  
      opam init
  
      brew install rlwrap
  
  5. Install batteries-included (ocamlfind will be installed automatically)

      Put the following in ~/.ocamlinit
  
      #use "topfind";;
      Toploop.use_silently
               Format.err_formatter (Filename.concat (Findlib.package_directory
               "batteries") "battop.ml");;
  </code></pre>
