I know this doesn't help you anymore, but it's a widely spread misconception that most people try to install the newest software on their systems (sometimes even production systems), even if the old software is working perfect, and risk the loss of their systems.
Never touch a running system. It doesn't matter if you're running CentOS 4.2 or 4.3, Fedora 4 or 5, etc. What is important is that the system is working reliably, and not that you have the newest software. You should use Debian, and you'd learn that stability is worth far more than bleeding-edge software.
