Ok, I added an extra test to unmemocopy (to test that the argument is null), 
and now I get

Backtrace:
In unknown file:
   ?: 0* (define begin-deprecated (procedure->memoizing-macro (lambda # #)))

<unnamed port>: In expression (define begin-deprecated 
(procedure->memoizing-macro #)):
<unnamed port>: Unbound variable: define


Hope that means more to you than it does to me!  I don't understand why I 
needed to
change unmemocopy though.
