title: Perl DateTime::TimeZone not found (Bugzilla install)
body: <p>I am trying to install Bugzilla on my Centos server. but I got this error:</p>
  
  <pre><code>Checking for   DateTime-TimeZone (v0.71)    not found 
  </code></pre>
  
  <p>and</p>
  
  <pre><code>    COMMANDS TO INSTALL REQUIRED MODULES (You *must* run all these commands
      and then re-run this script):
      /usr/bin/perl install-module.pl DateTime::TimeZone
  </code></pre>
  
  <p>If I run: <code>/usr/bin/perl install-module.pl DateTime::TimeZone</code></p>
  
  <p>then I get this:</p>
  
  <pre><code>    CPAN: Storable loaded ok (v2.15)Reading '/root/.cpan/Metadata'
      Database was generated on Sun, 09 Oct 2011 17:27:24 GMT

      CPAN: Module::CoreList loaded ok (v2.56)
      DateTime::TimeZone is up to date (1.39).
