If you're running RH the easiest way is... uh... rpm -uvh? Something. Anyway, there's an uninstall command for rpm's. If your compiling from source you could see if 'make uninstall' works or - too late, but - get 'checkinstall' and it will turn tarballs into slackpacks or rpm's or whatever and they're uninstalled with the package manager.
