I've taken another look at the setup here. xterms work adequately in the
vnc desktop for my needs, e.g. top and vi work as expected and the only
failing I've seen is that mutt was unusable as the text was not visible.
I've not pursued that issue since it's not a problem for my needs.

Here's some of the configuration on the system I referred to:

        # crontab -l -u ws
        # 20080330 ws - vncserver bombs without /usr/local/bin (for xauth) in PATH
        # 20080329 ws - /usr/X11R6 is now /usr/local
        @reboot /usr/local/bin/vncserver :1 -geometry 1024x768 -depth 16

        # cat /home/ws/.vnc/xstartup 
        xrdb $HOME/.Xresources
        xsetroot -solid grey
        xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
        env DISPLAY=:1 wine c:/utorrent.exe &
        lwm &

        # ls /etc/X11/*
        ls: No match.

        # ls /home/ws/.X* /root/.X*
        /home/ws/.Xauthority    /root/.Xauthority

I don't recall the history of the xrdb and xsetroot lines in xstartup,
but neither is currently installed nor required - hence the errors for
those in my previous message.

x11/rgb isn't installed and the only other port I can recall
deliberately installing was x11-wm/lwm (actually a couple of other
light-weight window managers, too, but I currently use lwm). 

The system was running 6.x until yesterday when it was upgraded to
7-STABLE with no discernible change in behaviour, albeit the ports are
yet to be updated.

Some additional information is needed to narrow this down. What exactly
did you see the xterm (and others) complaining about? System and ports
versions? Are you running vncserver as root or user?
