Er. If whoever's operating the machine is smart enough to look through /usr/lib for broken links (and then fix them), surely they're smart enough to have fixed it and circumvented the parental policy in the first place?
I wholeheartedly echo the "don't mess with the filesystem" advice. There's a dozen different, better, less brittle ways of doing what you want, even PolicyKit (/me shudders).

This isn't Windows. Unless the .so you broke was for a device driver (dynamic libs in userspace for a device driver? I don't think so), "reinstalling" the device won't fix the problem. Assuming that you did, indeed, break a .so link, you've got to fix the link or, failing that, find which package it was in and reinstall the package (hoping it doesn't blow up because you've changed the state of reality out from under it).
