How do I uninstall/remove binary/source packages?

Some times a package has a make uninstall built into it. If it doesn't then you have to find the files and delete them. I don't know how SuSE manages packages, but in Slackware there is a tool name pkgtool where you can uninstall packages from or removepkg nameofpackage

For general source installations, you might consider installing checkinstall, which is two scripts: checkinstall and installwatch. Whether or not you use checkinstall to make rpm/deb/slack packages to install, the installwatch part is still useful. You invoke installwatch -o <filename> <installfile> to make a file listing <filename> everything installed from the source package <installfile>. If that package does not contain an uninstall script, the file you created with installwatch makes it trivial to write your own uninstall script, taking input from <filename>.

Note: I just checked the checkinstall website. You can get installwatch seperately from checkinstall.
