Can not run ActiveRecord tests under 1.9.2

The tests for ActiveRecord will not run due to some loading issue under 1.9.2 because it complains about a NameError when loading ActiveSupport. I think this is a general load error and nothing specific with the OrderedHash namespace. If someone could give me some guidance on what might be causing this, I would be happy to investigate and provide a patch. Note, I have confirmed this on all my computers. Initially I thought it was "just me". Here is the stack trace I see.
