[racket] using scribble/eval in conjunction with scribble/lp

I tried and failed to figure this out. In particular, when I create the
example "lp.rkt" file described at the top of the scribble/lp docs and
require it "in the normal manner", the identifier f is unbound for me.

The code I'm using is pasted below:

;; lp.rkt
#lang scribble/lp

Literate programs have chunks of code, like this one:

@chunk[<f>
       (define (f x)
         <fs-body>)]

and this one:

@chunk[<fs-body>
       (* x x)]

that, when assembled, produce a complete program, in this case:

@racketblock[(define (f x)
               (* x x))]

-----

;; lp-test.rkt
#lang racket
(require "lp.rkt")
(f 3) ;; Error!
