Installing Additional Perl Modules

If possible, additional Perl modules should be installed via Ubuntu's apt-get command. For example, to install the Perl modules "Proc::ProcessTable", "Net::DNS", and "Net::Ping::External", run the following command (everything in one line):
sudo apt-get install libproc-processtable-perl libnet-dns-perl libnet-ping-external-perl

To install Perl modules where no packages for Ubuntu exist, run the following commands only once:
sudo apt-get install build-essential

Each time you want to install new modules, perform the following steps:

1. As a normal user (no root and no sudo), run the command cpan
2. Whenever you are asked a question, press Enter to accept the suggested default.
3. If you are running cpan for the first time, execute command make install
4. To install a new module, execute the command install Class::Name
5. Exit cpan by executing the command quit
