Script File discrepancy in Packt book: No FPSWalker file

OK, so I own Packt Publishing's Unity Game Development Essentials and Chapter 3 introduces Inspector components that don't quite match up with what I see in the Inspector of my Unity. I'm afraid it might be a Pro-vs-free version thing. One of the missing items on my screen is the FPSWalker file that suppose to go with the FPSWalker (Script) component of the inspector. My Inspector does not have an FPSWalker (Script) component when I select the first person controller. Speed and gravity are assigned through a Character Motor (Script) component. Any ideas? The errata for the book does not include this difference.

OK, so it looks http://answers.unity3d.com/questions/40430/fps-walker-script answers my question. Thanks anyway!
