Uninstall does not work well on Ganymede and Galileo, especially for GEP. It will uninstall GEP, but then you can't reinstall it, as it doesn't really get uninstalled. The only way to reinstall GEP in Ganymede is to reinstall Ganymede itself! It's the same for Galileo. See Eclipse Bugzilla 244935 for details, and hopefully a fix soon!
