If you are a Hostlantern customer, you can easily find all the Perl modules installed on your server. For this purpose you have to go to:
https://mydomain.com/cpanel/frontend/Crystal/perlmodules.html
The above will log you in your cPanel and all the Perl modules with their versions will be listed. Note that you should substitute mydomain.com with your domain.
Anyone else can find the available Perl modules by typing "instmodsh" in a Linux shell. This is an interactive Perl script which has the option "l" to show the available Perl modules.
