title: Why can't I find Perl modules after upgrading to Intrepid Ibex Ubuntu?
body: <p>I upgraded to Ubuntu Intrepid Ibex yesterday and suddenly some of the Perl modules that I installed (on the Hardy Heron) have all gone missing!</p>
  
  <p>I get the usual "Can't locate module in @INC" error. Has any of the CPAN repositories changed or something for Intrepid? Google doesn't help at all.</p>
  
  <p>Thanks in advance.</p>
