title: How do I install CPAN modules while using perlbrew?
body: <p>I have started using <code>perlbrew</code> and installed perl-5.12.2. </p>
  
  <p>I understand I need to re-install my CPAN modules, so I switched to my new Perl version (<code>perlbrew switch perl-5.12.2</code> and <code>hash -r</code>), verified the switch was successful (<code>perl -v</code>) then tried installing some module (<code>File::Copy::Recursive</code> using <code>cpan</code>. However, <code>cpan</code> says `File::Copy::Recursive is up to date (0.38).</p>
  
  <p>When I start a Perl script using this module, it shouts <code>Can't locate File/Copy/Recursive.pm in @INC ...</code> (showing many <code>perl-5.12.2</code> locations). When I switch back to my 'normal' Perl (<code>perlbrew off</code>) the script runs fine.</p>
  
  <p>Any suggestions? Perhaps CPAN does not work well with <code>perlbrew</code>?</p>
