title: Puppet : Specifying a version of a package to install
body: <p>Apparently this is not possible, but I can't believe that I'm the only one who need it.</p>
  
  <p>I want to specify the version of php to install because I'm working on an old project requiring php 5.2.</p>
  
  <p>Actually my VM is based on Oneiric with php 5.3</p>
  
  <p>Do you have any solution to do this ?</p>
