From the command line, as the root user, run:
# perl -MCPAN -e shell

cpan> install Module::Name
Alternatively, using sudo on one line, as any user you can directly intall a module by running:
sudo perl -MCPAN -e ‘install Module::Name’

Perl announced a couple of weeks ago that it is switching from Perforce SCM to Git. Is it time to review what SCM to use for managing distributed projects?
