Dear Justin,

     Thanks for all your information. I following the steps
https://github.com/jtgeibel/communityengine/blob/omniauth/README.mark...
, but i still have the errors when execute 'rake
community_engine:install':

     rake aborted!
undefined method `identity_map=' for ActiveRecord::Base:Class
g:/ror/Ruby192/lib/ruby/gems/1.9.1/bundler/gems/rails-1bedee56314f/
activerecord/lib/active_record/base.rb:1025:in `method_missing'

     I am wondering it is because the issue of rails 3.1.0.beta.
Following is the way i created my rails 3.1.0.beta:
     1. download the rails 3.1.0.beta ball from git-hub.
     2. "bundle all", then "rake build"
     3. go to dist directory, run "gem install rails-3.1.0.beta.gem

    I am confused, why we add following line into gem file. What is
different with the ball file version with bborn branch?
    gem 'rails', :git => 'http://github.com/bborn/rails.git'

     I might ask very stupid question, but please help me :). thanks a
lot.
