Hi Joshua,

There is a separate extension that should give you the picture language 
primitives you need.  See the PLT port of the picture language in the 
PLaNET package repository:

    http://planet.plt-scheme.org/300/docs/soegaard/sicp.plt/1/0/doc.txt

So in your own programs, the following s-expression:

     (require (planet "picture.ss" ("soegaard" "sicp" 1 0)))

should enable picture language support.


Best of wishes!
