You may be getting confused by the fact that most of the current MVC web tools (CGI::Application, OpenInteract, Catalyst) are fairly different from the approach described in the classic MVC theory articles. These days, MVC for the web usually means one class that handles all the web interaction (the controller), some fairly basic classes for updating a database with Class::DBI or similar (the model), and some templates (the view). It's not exactly MVC, but it's a simple approach that works well. If you look at some of the many sample apps written with any of the three tools I mentioned, you'll see this basic approach.
