If you get see the message
"Vendor library for driver MX11 not available", then
the problem is known about by AVS. According to
http://www.avsuk.com/support/tm/problems/7v2/ftbs/ftb723.htm,
This is because the order for resolving functions appears to have
changed in this release and AVS dummy versions of the X11 functions
are being used instead of the real ones from SGI. AVS provides dummy
versions of these functions for customers trying to link without X11
libraries. In previous releases the dummy functions were only picked
up if the real functions were not available.
