Unlike other aspects of PEAR development, the windows build of PHP 4.3.x is not tracked
   in CVS.  Instead, it is located on the machine that builds windows snapshots.  Often,
   this will not be updated when the rest of PEAR is updated.  Note that PHP 5.x releases
   use a different build system and are automatically updated to the latest versions of
   PEAR.
  
   If you find that PHP 4.3.x has out-of-date versions of packages, or no longer works, then
   please report that the windows bundle of PEAR is out of date to pear-dev@lists.php.net
