You would have to reinstall all of yout binary applications and libs, and the kernel.
It's easier and faster just reinstall the entire system. Just backup yout $HOME (don't forget the *.hidden* directories). You may also restore (reinstall) every package by saving a package list file (look at http://serverfault.com/questions/56848/install-the-same-debian-packages-on-another-system, not tested by me). -- Paulo Diovani, diovani.com / @paulodiovani <http://twitter.com/paulodiovani> / ♣<http://entbonsai.com>
