>  But Xcfbpmax from the X11R4 distribution gets a segmentation fault

Messages like this are far from useful.  The R4 server for a color 
decstation should run out-of-the box.  As I use a color PMAX on my desk,
I suspect this configuration was probably the most extensively tested of
all of the servers.

Please include a stack trace in messages like this; it's really not
that difficult to do:

	$ xinit -- ./Xcfbpmax
	Segmentation fault: core dumped
	$ dbx Xcfbpmax core
	...
	(dbx) where
	...
	(dbx) quit

At least that gives us an idea what troubles you're having.  Most likely,
the server is unable to locate some necessary resource.  Fonts or the rgb
database are frequently troublesome; make sure /usr/lib/X11 (or $(LIBDIR))
contain the appropriate files.  Note that the MIT server cannot use the DEC
server fonts; the formats are incompatible.
