I would start by not using the draw teachpack, nor the parts of HtDP that refer to it. Most of us have been doing graphics using the image, universe, and/or picturing-programs teachpacks instead for several years. One easy introduction to the currently approved approach is at http://www.picturingprograms.com/pdf . Another introduction (with less emphasis on graphics) is the sections of htdp2e that Matthias mentioned.
