Ok, mine was compiled for Ultrix 4.3 ...

Humm i hope X11R6 still implements the Ultrix 4.1 interface to, 
or i will have problems to get it running ...

For now I am to busy too. If i can't get the R6 server run, i'll

As i don't plan to keep any Dec running Ultrix, it is better to have
all binary in NetBSD format. X clients compile fine ...
