What did you try, and why do you think it didn't work?

1) `gem --help` should show you how to update gems
2) One of the whole points of using a VM like VirtualBox is the ability
to take "snapshots" of the state of the system. Install a fresh version
of VirtualRails, confirm it works, then take a snapshot.
Now you can do anything you like, and worst case you revert to
that snapshot. It's like git for your OS :-)
