Learning LISP

I've been making my way through SICP, I've reached a point where I feel I have to start experimenting with a Lisp compiler. I'm on a Mac so I downloaded LispWorks, I'm too lazy to figure out how this IDE works.

Can someone point me in the direction of a simple command line compiler/interpreter that will work with the SICP?

Don't forget, it was Microsoft, who forced C++ in the first place. And their .NET has only static typed OOP languages. They are embodiment of Satan himself. No coincidence, that all their executives're jewish.
