The last of these error messages indicates that AnswerBook is using NeWS
rendering in the viewer window.  Your users are going to have to run the
X/News server.  Changing from the MIT Xsun server to xnews is not a
significant change for your users: unless you have programs that rely
on server extensions other than MIT-SHM all X11R4 clients (including
window managers) will run as they did with Xnews.  The only perceptible
difference will be a decrease in speed on machines without GX boards
and an increase in speed on machines with GX boards.
