X11R4 on Xenix

[Paul Riethmuller SE Brisbane]

Sorry if this is a FAQ, but a week has gone by, and I have noticed
a couple of references to a port of X11 to Xenix.

Is there a version of X11 available (with ?pseudo socket library)
which I can run on my aging Xenix-386 machine.  I have SCO Xenix 2.3.1
OS with Development and Text systems version 2.2

Thanks
