Reinstall all rubies with rvm

When compiling ruby the executable is attached to various C system libs like libreadline. If libreadline is updated then each ruby on the system attached to the old libreadline must be re-compiled. If you are using rvm then this can be done with one command:

rvm reinstall all --force

The --force flag will skip any question the process asks.

Be careful, if you are working on a machine that has installed many rubies and has had many projects for those rubies this could take an extraordinarily long time.
