I understand that you are asking for experience, more than a technical answer.

I remember being scared of installing modules before using CGI::Application. This module makes you create your own module to work with it. You can't use it without calling your own module that is based on CGI::Application.

After loosing my fear on installing modules, I now, see them as a way of saving time in testing it all. And I am able to focus on the results.

I just install them where my script is, and they work the same!

If you rely on a module, you might rely on it's security also.
