Thanks for your reply. I found the package (rpm-build on rh) and installed it from the CD. Now when I try to build the rpm's from the source I'm getting errors like the following:
#error to build against currently running kernel
install: cannot stat 'NVdriver': no such file or directory
RPM build errors:
bad exit status from /var/tmp/rpm-tmp.82603(%install)
What could I have done wrong?
