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?

LispWorks if for Common Lisp.
You want Racket or MIT Scheme for SICP.
I would heavily recommend learning CL too, but SICP is Scheme, not CL.
