title: php 5.2.5 on Centos 5.4
body: <p>My client is using Centos 5.4 which has PHP 5.2.4.
  We wish to use Drupal 7 for one of his site, however Drupal 7 needs PHP 5.2.5.</p>
  
  <p>I tried to update the php version in Centos using yum but I get something like:
  No Packages marked for Update</p>
  
  <p>Is there anything I can do to get PHP updated to the proper version?</p>
  
  <p>Thanks</p>
  
  <p>Hugo</p>
