Perl modulos Cpan GNU/Linux

Linux CPAN (Comprehensive Perl Archive Network) es una gran colección de software y documentación PERL, que permite de un modo extremadamente sencillo la instalación de módulos Perl.
Como root el siguiente comando para seguir un asistente con unas preguntas bastante intuitivas, despues de hacer una busqueda de mirrors cpan queda instalado en su servidor y es posible seguir la instalación de los modulos que quiera hagamoslo:
# perl -MCPAN -e shell
CPAN is the world-wide archive of perl resources. It consists of about
300 sites that all replicate the same contents around the globe. Many
countries have at least one CPAN site already. The resources found on
CPAN are easily accessible with the module. If you want to use, lots of things have to be configured. Fortunately, most of
them can be determined automatically. If you prefer the automatic
configuration, answer 'yes' below.
If you prefer to enter a dialog instead, you can answer 'no' to this
question and I'll let you configure in small steps one thing after the
other. (Note: you can revisit this dialog anytime later by typing 'o
conf init' at the cpan prompt.)
Would you like me to configure as much as possible automatically? [yes] yes
Autoconfigured everything but 'urllist'.
Now you need to choose your CPAN mirror sites. You can let me
pick mirrors for you, you can select them from a list or you
can enter them by hand.
Would you like me to automatically choose the best CPAN mirror
sites for you? (This means connecting to the Internet and could
take a couple minutes) [yes] yes
