Weird but functional output on terminal about betty

It seems there is a problem with the new ruby hashes. Can you give us your ruby version? And if it is below 1.9, updating should fix your problem.

You were right:
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]
It's weird since my repositories were updated before installing it today and when reissuing an install says:
"luis@epsilon:~$ sudo apt-get install ruby
Reading package lists... Done
Building dependency tree
Reading state information... Done
ruby is already the newest version."
Will try to manually update ruby and let you know.

UPDATE: After manually updating to ruby 1.9.1 works normal

Similar error and had the same resolution.
Was trying to run this on Backbox 3.1.3 (Ubuntu 12.04) and had similar output but as suggested, manually updated from Ruby 1.8.x to 1.9.x and once I updated the alternatives it works just as expected. Thanks!
