[plt-scheme] Using teachpacks with Mzscheme

I was wondering if there was a way to use the teachpacks within mzscheme.

I have tried putting this at the top of my file:

(require (lib "mred.ss" "mred"))
(require (lib "draw.ss" "htdp"))


Welcome to MzScheme version 202, Copyright (c) 1995-2002 PLT
 > dynamic-require: unknown module: #%mred-kernel
 > reference to uninitialized module identifier: cursor% in module: 
|,/usr/local/lib/plt-202/collects/mred/private/kernel|
 >

I am obviously doing something wrong and am busy with the mzscheme 
manual, but any help would be appreciated.

tia,
