Actually this only seems to work when run from within DrRacket.  The 
following example works fine from DrRacket, but gives an error from the 
command line using raco scribble:

namespace-attach-module: a different module with the same name is 
already in the destination namespace

#lang scribble/manual
@(require scribble/eval)
@(define the-eval
   (make-base-eval #:lang 'racket))

@examples[#:eval the-eval (add1 7)]

It's not at all clear to me how to resolve the problem.
