How do I get a scheme interpreter working inside Emacs?

Question

I'm going through SICP and I'd like to have an interpreter analogous to the interactive Python interpreter to play around in while I'm watching the lectures and reading the book. Furthermore, I'd like this interpreter to run inside Emacs so I can jump back and forth between files of scheme code and the interactive interpreter and so forth.

However, I'm fairly new to Emacs and have not as of yet been able to get this to work or find one clear set of instructions to use in getting it to work.

It seems like I should be able to set it up so that M-x run-scheme will open up an interactive interpreter that at least sounds like exactly what I want, but at the moment this just returns Searching for program: no such file or directory, scheme and I haven't been able to figure out exactly what files I need to put where to remedy this.

I'm running GNU Emacs 22.1.1 (mac-apple-darwin, Carbon Version 1.6.0) as installed through the OS X 10.5 install DVD.

You need to install a Scheme interpreter like MIT Scheme (which is the recommended implementation for going through the SICP exercises). On Ubuntu it comes with a symbolic link called "scheme" which is what Emacs is looking for. You can download it for MacOS X here.
