Whatever that module outputs, it is very unlikely that this is a comprehensive list of all modules. But if that is so, then your installation of Perl lacks many modules shipped with a standard Perl, and you should complain to your package or OS maintainer (commonly called "vendor") that they should fix their distribution.

If you're going the route of compiling and installing your own Perl, make sure not to install it over the system Perl. The best way is to not run anything as the superuser. If you install your own version of Perl, you get all those modules and also get full control over what goes where.
