Also from the Faqs...
In an object-oriented language such as Java, if I use a class that is GPL'ed without modifying, and subclass it, in what way does the GPL affect the larger program?

Subclassing is creating a derivative work. Therefore, the terms of the GPL affect the whole program where you create a subclass of a GPL'ed class.

If I interpret this correctly, this means you can't use a GPL'd module in a non-GPL'd program, does it not?
