Looks like some changes made in the Ennumerable extensions had some
majorly negative effects on the Summing ability of AR.

Sample Errors off mysql:

  2) Error:
test_should_group_by_summed_field_with_conditions_and_having(CalculationsTest):
ArgumentError: wrong number of arguments (2 for 0)
    ./test/../lib/active_record/associations/association_proxy.rb:123:in

Working on a way around this right now....

Enumerable#sum was overriding AR::Calculations#sum. I opened a ticket
for this (#5500 [http://dev.rubyonrails.org/ticket/5500]) with a patch
which manually routes #sum to #calculate in AssociationCollection. The
unit tests all pass now (MySQL).

This patch fixes the errors I was getting.
