If you do not already have binutils, you may download it from any Redhat Linux mirror. This link
should lead you directly to the file you need. Download it, su if necessary (I'm quite sure you'll need root privileges to install this package), and type rpm -ivh binutils-220.127.116.11.2-11.i386.rpm
to install it. Upon successful completion, attempt to run the nVidia installer again and see what happens.
