title: How to upgrade a package in linux that was built from source?
body: <p>I downloaded Boost v1.42 source and then installed it in my laptop. I want to upgrade them to v1.45 (the current release). I would like to know how I can do this via command line. This question applies to any package built from source and installed in a Linux machine.</p>
  
  <p>Any help is greatly appreciated.</p>
  
  <p>Cheers...</p>
  
  <p><strong>EDIT-1:</strong> The distro I am using is CentOS 5 on my laptop and Debian Lenny on my PC.</p>
