Grass on RS6000 Help?

[Thomasd Kuerschner]

Hello!
We are an institute of project- and regionalplanning at the university Giessen
in Germany. We work with GIS since one year. Now we try to install GRASS4.1
from cecer.* on our workstation IBM 220 with AIX. 
Can anybody give us a review, because we are no specialists, 
or an adress for a complete binary version?
Many thanks in advance!
