title: How to use a CPANPLUS autobundle to update a new version of Perl?
body: <p>I have Perl 5.13.4 with a large collection of installed CPAN modules.</p>
  
  <p>I have just compiled Perl 5.14.0.  I'd like to install (recompile) all the modules in 5.13.4 into 5.14.0.</p>
  
  <p>I can/have generated a bundle of the installed modules with 'cpanp' and the 'b' option; I now have a file <code>~/.cpanplus/5.13.4/dist/autobundle/Snapshot_2011_05_18_00.pm</code>.</p>
  
  <ul>
  <li><p>What is the command to use in the 5.14.0 version of 'cpanp' that will go through that snapshot bundle and ensure 5.14.0 has all those modules installed?</p></li>
  <li><p>Or, if the combination of cpanp and a bundle isn't the appropriate way to go, what is the easiest way to replicate (recompile) the modules installed in the old version of Perl for the new version of Perl?  (If CPAN can deal with the bundle file, I'll use it - it is the result I care about, not the mechanism used to achieve it.)</p></li>
  </ul>
  
  <p>(<em>I did take a quick look at the list of questions for 'perl cpanplus bundle' here on SO without finding the information I'm after.  I've also looked at 'perldoc cpanp' on several occasions and failed to find the information I'm after.  That isn't the same as saying "the information is not there"; it may simply mean I've not spotted it.</em>)</p>
