Unclear exception for non-existing aliases

[tenderlove]

This should have been fixed in Psych 1.2.1. Can you try on Ruby 1.9.3? The current exception should look something like this:

irb(main):003:0> require 'psych'
=> true
irb(main):004:0> Psych.load "foo:
irb(main):005:0"   <<: *bar"

Make sure you do:

gem 'psych'

before you require it, or use edge 1.9.3
