lots of others with same problem, doesnt look good either, typical redhat dependency issues and crappy support
dont think what you need is on your install disk by the looks of it, not sure what to tell you exactly, it looks like uninstalling X and changing to another version MAY work, but it may break other things in the process, my best advice is dump it, download a better supported and widely used distro, my recommendation is slackware, but getting everything to work right after install takes a bit of know how sometimes, but at least it comes with EVERYTHING, and its the most popular distro made, killer support, and even their website has everything available for download right there.
