problems installing Xgrass

I am trying to install Xgrass on our SUN4 SparcStations SunOs 4.1.3
grass4.1 is already working fine, but we want to use Xgrass in the future.

We tried to compile but hardly anything happend.
[grass@:/src/xgrass] gmake4.1
  SRC = /tools/grass/src
  CMD = /tools/grass/src/CMD
  HEADER = sun4
  ARCH = sun4
  GISBASE = /tools/grass/sun4
  VERSION = 4.1 Spring 1993 Update package 3
#################################################################
/tools/grass/src/xgrass
  mkdir OBJ.sun4
  make -f OBJ.sun4/make.rules

rm -f /tools/grass/sun4/etc/databases
echo /tools/grass/databases > /tools/grass/sun4/etc/databases
rm -rf /tools/grass/sun4/etc/xhelp
tar cf - ./xhelp | (cd /tools/grass/sun4/etc; tar xf -)
rm -rf /tools/grass/sun4/etc/app-defaults
tar cf - ./app-defaults | (cd /tools/grass/sun4/etc; tar xf -)
rm -rf /tools/grass/sun4/etc/xclip
tar cf - ./xclip | (cd /tools/grass/sun4/etc; tar xf -)
[grass@:/src/xgrass]

We could not figure out the meaning of this.

Can any body help us
all path in the compiler are wrong we use LD_LIBRARY_PATH=/usr/lib:/tools/lib:/
usr/lib/X11:/usr/X11/lib
Grass home: /tools/grass

Many thanks in advance
Eric
