The next time you install a new module that also requires those same dependencies, Perl will see that you already have them and they won't be installed again.

Unless of course that new module requires more recent versions of those dependencies.

A long time ago when computers were not so powerful, there was concern about loading too many modules (whether directly or as dependencies) because your script could be slow to compile. But unless you are in a very specialized situation this should not be a concern either.

That's a bit more contentious. Quite a lot of the time I avoid long (and broad) dependency chains. Reasons for this include:

Given predrag's stated aim of investigating CGI then all of these points become relevant for him, I would suggest.
