title: What modules are distributed with Perl?
body: <p>How do I know what modules are distributed with Perl?</p>
  
  <p>My first guess is that the core modules listed <a href="http://perldoc.perl.org/index-modules-A.html" rel="noreferrer">here</a> are always included, though I cannot find this stated explicitly. However, I have used modules outside this set (e.g. LWP) without having to install them on Mac OS X and Linux.</p>
  
  <p>So to refine my question a little: </p>
  
  <ul>
  <li>What modules are distributed with all Perl installations?</li>
  </ul>
  
  <p>And: How do I find out what modules have been distributed with:</p>
  
  <ul>
  <li><p>Linux (particularly Debian/Ubuntu)?</p></li>
  <li><p>Mac OS X?</p></li>
  <li><p>Solaris?</p></li>
  </ul>
  
  <p>In each case I am using the version of Perl that comes standard with the most recent version of the operating system.</p>
  
  <p>TIA.</p>
  
  <p><b>Update:</b> The reason for the question is that I am developing on Mac OS X and Linux for deployment to different Linux and Solaris, and I don't have root on some of these systems, and in the case of Mac OS X I don't even have a compiler AFAIK. So what I want to know what modules I have available in all four deployments without further installs.</p>
