title: How can I install a specific version of a set of Perl modules?
body: <p>I'm tasked with replicating a production environment to create many test/sit environments.</p>
  
  <p>One of the things I need to do is build up Perl, with all the modules which have been installed (including internal and external modules) over the years. I could just use CPAN.pm autobundle, but this will result in the test environment having much newer versions of the external modules that production has.</p>
  
  <p>What is the easiest/best way to get and install (a lot of) version specific Perl modules.</p>
