cvsup fails because of xlib connection error

[chip]

I just set up a new box using FreeBSD-5.2 and install cvsup. Now when I 
run cvsup I get this -

chip3# cvsup ports-supfile
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Lost the connection to the X server

I have this in my /etc/hosts file (probably more than necessary, but I 
was just trying to cover all my bases) -
#
::1                     localhost localhost.wiegand.org
127.0.0.1               localhost localhost.wiegand.org
192.168.0.7             chip3.wiegand.org
127.0.0.1               chip3   chip3.wiegand.org
10.0.0.1                chip3   chip3.wiegand.org
#

What have I screwed up and how do I fix it?
thanks,
Chip
