I saw something like that the other day, but I was developing a GUI in  
DrScheme, so I added:

#lang scheme/gui

to the top of my file and the error went away.  It sounds like you're  
doing something different and you're in EOPL3, but maybe this is a  
clue.  I last updated from svn a couple of weeks ago.
