info request for prescheme compilr

I've been reading through the Prescheme code included in scheme48 and
have been unsuccessful with getting a simple test proc compiled.  I'd
hacked up a build script similar to what's in the makefile but keep
getting unknown symbol errors.  Is a trivial example available?
(e.g. compile `(define (hello) "hello world")' to C.)
