Below are Perl modules that do not come with a standard installation of Perl 5.6.1. They may exist in 5.8.x versions but if you are not sure in any case, please download them anyway. Each one of these are used extensivley and Manatee will not function without them.
The below modules are required by Manatee only. However, each individual module may have it's own perl module prerequisites and dependencies to work properly. If that is the case, simply download and install those prerequisites before attempting to install the next module in the list.
