To install GRASS on your SuSE 9.2, download and install in the following order:
* proj-4.4.9-1.i586.rpm
* gdal-1.2.5-1.i586.rpm
* grass-6.0.0-1.i586.rpm
* gdal-grass-1.2.5-1.i586.rpm
* geos-2.0.0-1.i586.rpm
* qgis-0.6.0-0.i586.rpm
The files are here:

If it's still bitching about grass libraries, then get these:
http://www.gdf-hannover.de/software/suse/9.1/SRPMS/
rpmbuild --rebuild grass*src.rpm
rpm -Uvh /dir/files_that_it_just_wrote/*.rpm
That should do it. Hell, you could recompile it all from source- and probably should- since it's for 9.1 and not 9.2.
