You can use perldoc -m to see the package's content:

$ perldoc -m CGI
package CGI;
require 5.004;
use Carp 'croak';
...

Or the -l switch to see where the package is:

$ perldoc -l CGI
/System/Library/Perl/5.10.0/CGI.pm

You can also find all the source at CPAN. Just looking at a single file in isolation generally isn't that fruitful, you'll want to look at all the files in the distribution as a coherent whole.

You'll probably want to familiarize yourself with the other things that perldoc can do:
