xgrass4.1 on SPARC Solaris2.4

I'm new to GRASS.
I succeeded to compile grass4.1 and Xgrass4.1 on my Solaris/sparc machine. Xgra
ss starts up fine,
but I can't input from the keyboard. Pressing a buttom simply has no effect at
all.

Following the installation instructions, I guess I'm at the end of the installa
tion - or not?

Got anybody an idea ?
Thanks

Joe
