Install macports http://www.macports.org/

Then
 $ sudo port install ocaml
 $ sudo port install pcre
 $ sudo port install cairo
 $ sudo port install gtk2

=> can configure and build all pfff tools :)

Troubles ?
--------------

- If you have problem installing cairo and get an error message like:
  "Error: db46 requires the Java for Mac OS X development headers.
  Error: Download the Java Developer Package from: 
  <https://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wa/getSoftware?bundleID=20719>"
  "
  then follows the link and install the Java Developer Package.

  An alternative fix may be to reinstall XCode as indicated at:

- If you have problem installing gtk2 and get an error related to atk,
  do: 
    $ sudo port install gobject-introspection 
  and
    $ sudo port install gtk2
  again.

- If you have a problem when compiling pfff in its external/ocamlgtk directory
  with an error like:
  "Error: Error on dynamically loaded library: 
   ./dlllablgtk2.so: dlopen(./dlllablgtk2.so, 138): 
   Symbol not found: _g_simple_async_result_take_error"
 do:
   $ sudo port selfupdate
   $ sudo port upgrade outdated
 which should update glib2 and fix the bug.

- For cairo and gtk don't use the quartz setting as it is currently
  buggy under macports.
