Hello, there is no Xgrass distribution on topquark, because Andy Burnett has no Motif License. I will put an Xgrass-port to Linux on ftp.uni-erlangen.de soon, but be aware, Xgrass on Linux will not run properly! Try tclgrass instead of Xgrass, You will find Xgrass-source and tclgrass besides the whole GRASS source on moon.cecer.army.mil
