Rspec + Shoulda + FactoryGirl = undefined method `reflect_on_association'

Question

I have Rspec + Shoulda + FactoryGirl and I am receiving the following error when attempting to call Shoulda's have_many or belong_to methods. All Shoulda methods used in the "validations" group work fine:

Thanks in advance

spec/spec_helper.rb

require 'shoulda'

spec/models/project_spec.rb

require File.dirname(__FILE__) + '/../spec_helper'

describe "A Project" do
  describe "associations" do

    subject { Factory(:project) }

    it { should have_many(:tasks) }
    it { should belong_to(:project_status) }
  end

  describe "validations" do
    subject { Factory(:project) }

    it { should validate_presence_of(:name) }

    it { should validate_uniqueness_of(:name).case_insensitive }

    it { should allow_mass_assignment_of(:name) }
  end
end

Thanks to David C. for pointing out what should have been obvious. I had a redundant active_matchers plugin that was conflicting with shoulda.
