[plt-scheme] web-server needs X?

Hi there,

I am trying to run the plt web-server (v208) on a FreeBDS 5.2.1 box. I 
am probably going to show my Unix ignorance, but I am having some 
trouble running web-server without an X server:

gondor# echo $DISPLAY
DISPLAY: Undefined variable.
gondor# ./web-server
DISPLAY environment variable not set and no -display argument

If I use another box as an X server and set DISPLAY appropriatly 
web-server starts just fine, but I see no windows opening.

Am I  doing something wrong or is this dependence for real?
