How to install missing Perl modules on Debian

Use aptitude to see if a prepackaged version exists
- if the module name is Foo::Bar the packaged version will be called libfoo-bar-perl
- so do 'aptitude search libfoo-bar-perl'
- or just 'aptitude search foo-bar'
if found, use apt-get to install it
- 'sudo apt-get install libfoo-bar-perl'
if not found, install from CPAN
- 'sudo dh-make-perl –install –cpan Foo::Bar'
if that doesn't work for some reason
- 'sudo cpan Foo::Bar'
