[plt-scheme] Literate Programming

I've a scheme file chunked up; i.e. all functions are enclosed in
@chunk[<chunk-name>] wrappers. I've a second file:

#lang scheme
(require scribble/lp-include)
(lp-include
 "repl-2.ss")

When run the second produces:

"\n"
"\n"
#<splice>
"\n"
"\n"
"\n"

etc.

What am I doing wrong?

--hsm
p.s. first file starts with #lang scribble/lp
