How did you install WWW::Mechanize::Plugin::FollowMetaRedirect? Usually, Perl modules list all the other Perl modules they rely on and the Perl installation mechanisms follow these so-called pre-requisites and install them as well.

If you did not use the installation mechanisms provided by Perl (cpan, cpanp or cpanm), please use them.
