The "bind97" packages is in RHEL 5.6. RedHat pubishes such major component upgrades as separate packages, so people using the older version get updates, but who want the major upgrades are free to install them and get separate support. Our faithful CentOS maintainers have not yet completed their publication of CentOS 5.6. I'm sure they'd appreciate your help doing so, although I've had some difficulty reverse engineering enough of their build structure to parallel their work.
