G'day perldb2,

-- Downvoted! You asked about this topic, and got a solution, a few weeks ago in "OSX Server Perl install modules".

You did not get the output you claim from:

perl -MCPAN -e 'CGI::Application'
[download]

Here's what I get (i.e. no output):

$ perl -MCPAN -e 'CGI::Application'
$
[download]

Similar commands also producing no output:

$ perl -MCPAN -e 1
$ 
$ perl -e 'CGI::Application'
$ 
$ perl -e 1
$
[download]

The remainder of my post is what I wasted my time on before realising you'd already been given this information.

I'll assume "MAC MINI" uses Mac OS X: please correct me if I'm wrong. I don't which version you have and this is important: please advise.

Apple has installed its own version of Perl for its own use. This is generally referred to as the "System Perl". Do not modify (add, change or delete) the System Perl: it can affect how the OS currently runs; your modifications will probably be overwritten by the next update. I'd recommend perlbrew: I've been using this for over five years on various Mac OS X versions.

See also: CPAN on El Capitan and OSX Server Perl install modules.

Chiming in on the sudo solution. This will work for a lot of things on OS X—i.e., installing as root—but you will eventually hose your system perl when you get into XS and linked library modules. Never mess the system perl on Mac. Always use a local user-owned perl. I suggest a combination of perlbrew, cpanm, and local::lib.

Update: I would also recommend not using CGI::Application. The newer frameworks like Dancer2, Catalyst, and Mojolicious are better (if perhaps costing more upfront in learning-curve).

Either sudo cpan... or whatever to gain permission to install the module in /Library...

Or install the modules in a different location, like your home directory

To learn how read Re: How to install modules for local perl without changing anything on system perl?

You will have maximum control of your local deployment and can scale from there. CGI::Application is good for an environment where you're bound to the Apache stack, but if you're not (i.e., local development), Dancer2 is the way to go.
