Got this too and think it came down to not having enough of the right RedHat-8.0 RPMS installed for compiling. I then installed kernel-source, zlib-devel, glib-devel, glib2-devel, pkgconfig, gcc-c++, compat-gcc-c++, compat-libstdc++-devel, libstdc++-devel, compat-gcc, gcc, binutils. Perhaps somewhat overkill for this, but I'll need them someday anyway.
Even so, I have not gotten 3123 to work with a GF4 Ti card. One time it threw the machine into a reboot time loop. I tried recompiling the 2960 nvidia packages but they don't work: 'modprobe NVdriver' complains about inserting gcc-2.x modules into a gcc-3 kernel, which is now strictly verboten.
