Latest 2.3 rails

Cloud Crowd's gemspec requires activerecord ~> 2.3.  Therefore when the
cloud-crowd gem is installed, it retrieves the latest active record &
activesupport(a dependency of activerecord), which in this case is
2.3.18.

Then when rake cloud:server:start is called later, ruby gems has already
activated activesupport 2.3.18, but the enviroment.rb is requiring
2.3.17.

Unable to activate rails-2.3.17, because activesupport-2.3.18 conflicts with activesupport (= 2.3.17), activerecord-2.3.18 conflicts with activerecord (= 2.3.17) (Gem::LoadError)
