[Bug 1389596] [NEW] upgrade removed ruby

[Adrian Bridgett]

Public bug reported:

this morning our machines performed security updates.  As a result of
this we lost /usr/bin/ruby (it was just non-existant)

This seems to be when ruby package is upgraded _before_ libruby1.9.1.

Reinstalling the ruby package fixed this.

dpkg.log follows (you can see my manual reinstall of ruby at 09:35):
