>&#13;      Certain older versions of the CPAN toolset were somewhat naive about how
      to upgrade Perl modules. When a couple of modules got rolled into the core
      Perl distribution for 5.6.1, CPAN thought that the best way to get those
      modules up to date was to haul down the Perl distribution itself and
      build it. Needless to say, this has caused headaches for just about
      everybody. Upgrading to a newer version of CPAN with the
      commandline above should fix things.
