while that's the case for windows and internet explorer et c, i think it's untrue for linux.
I was looking through what's on my turbolinux and red hat install cds a day or 2 ago, and all the "default" stuff is right there as rpms. all the "default" install does is run rpm, i think (am i right, folks?) so you should be able to use rpm to uninstall it? did you try to do that and fail? if so then it's beyond my limited knowledge i'm afraid [img src= a shrugging emoticon (we need one of those!)]
