title: Php 5 on RedHat Enterprise Linux 5
body: <p>By default, RHEL5.x64 comes with 5.1.6 - pretty old.  I'm looking for a more up to date version, 5.2.8, or even the latest 5.2.9 (as of March 2009). Ideally, a Yum/RPM-based solution, for transparent upgrades (when I plan).</p>
  
  <p>How do you upgrade the default for an up-to-date version?</p>
