need a bit more info, specifically the distro you are running. if it's an rpm, you can pass the --nodeps option:
rpm -Ivh --nodeps rpmname.rpm
to bypass the dependency checking of rpm. with the nvidia drivers, installing the Mesa libs will corrupt the nvidia opengl libs. if you are on a distro that has an auto updater like up2date or whatever, whenever new updates are available make sure mesa or glut are not in the list of packages to be installed.
