Installing Perl Modules.
Perl Modules can be obtained from the CPAN (Comprehensive Perl Archive Network) at http://search.cpan.org.
The easiest way to install Perl modules on Unix is to use the CPAN module. For example:
cpan> install DBI
cpan> install DBD::mysql
DBD::mysql is the Perl5 Database Interface driver for the MySQL database.
To find a particular module, use the i command, followed by an expression that you want to search for:
CPAN.pm will go out to the CPAN mirrror that you selected, download the list of modules, and tell you which ones match the search word.
To install a module, just type:
CPAN.pm takes care of the whole process. It downloads the compressed file, unpacks it, builds it, and installs it all for you, unless there is a problem with the installation process. If there are other modules on which this module relies, it will also download and install those.
