Since the problem is when linking with gs, it's a new problem (unless 
you have built with gs previously).

The problem is that libgs.so is linked with libX11.so.4 which is the 
openwin version and if you link with that lib it needs libXext.so.0 from 
the same place. But when linking with CSW X11 there exists a CSW version 
of that lib that doesn't contain XSolarisIASetProcessInfo.

You can either wait for James to rebuild ghostscript or try to link with 
  /usr/openwin/lib/libXext.so.
If you want to try the second option, I've sometimes successfully 
managed to do it by adding the following to my Makefile.
EXTRA_LINKER_FLAGS = /usr/openwin/lib/libXext.so
Others have solved it by adding
EXTRA_LDFLAGS = /usr/openwin/lib/libXext.so
