[Mimedefang] Useful perl command: list module versions and compare to CPAN

I was trying to determine what versions of which modules were
installed on my instance of perl, to prepare for a Mimedefang upgrade.
 I searched this list, and found several posts showing various ad-hoc
ways of getting this information, and then I found this gem on IBM's
support site:

perl -MCPAN -e 'CPAN::Shell->r'

You need to have CPAN/Config.pm, which the CPAN module will create
first time it is invoked. I think you will find this much more
satisfactory than other methods posted to the list before.
