Installing Perl modules
As always with perl, there’s a couple of options 
Automatically using CPAN perl -MCPAN -e shell install Perl::Module::You::Want
Automatically using g-cpan in Gentoo g-cpan -i Perl::Module::You::Want
Semi automatically in Debian
- find a “lib-module-you-want-perl” module that provides the package you want.
- command apt cache search “lib.*-perl” gives you a list of all prepackaged perl modules.
- install “apt-get install”
By hand, described here.
