For R5RS, you will want to add SRFI-6 to do this (you should always add 
SRFI-23 and SRFI-6 to R5RS), and then just use the "write" procedure to 
write to the output-string output-port.

That also happens to be a good way to do it in Racket, unless you want 
to use the very nice Racket pretty-printer.
