No.
The doc is installed with the module. But nothing prevents from deleting the
module or just installing the doc.

You can look for modules by hand, for example with
$ find /usr/lib/perl5/ -name DBI.pm
Or (more reliable) you can check if modules are installed by trying to load
them:
$ perl -le 'use strict; use warnings; use DBI;'
If no error occurs, the module is installed.
