SOLARIS 2.3 GRASS Question

In The January 1994 grasshopper archive, Ye Qi writes:

GRASS was working very well until I replaced Solaris 2.2 with 2.3.
Now I cannot start the graphics monitor.
I got the following message while running d.mon:

---------------------------------------------------------
ld.so.1: x0: fatal: libX11.so.4: can't open file: errno=2
Killed
Please start graphics monitor <x0>.
Error - Graphics monitor <x0> not running!
Problem selecting x0. Will try once more
Please start graphics monitor <x0>.
Error - Graphics monitor <x0> not running!
----------------------------------------------------------

I have EXACTLY the same problem with our SOLARIS 2.3 SUN.
No response appeard in subsequent grasshopper archives.
If somebody does know the solution to this, please post it!
Thanks in advance!!!
