troubles with compiled grass 4.1

[Maurizio Caselli]

I got the binary version of grass 4.1 for solaris.2.x.
When I try to install it, (sol.4.README), I should find the files :
grass4.1, xgrass 4.1 and etc/monitorcap. 
In these files I must change the value of GISBASE.
WHere I can find these files?

thanks in advance
