[release 1.2] rspec failing

[nmccready]

What are the steps to get this working? I ran bundle install and all seemed well when the dm-core version was bumped to >= 1.2.1. However I keep getting the following error on running specs.

Users/nem/.rvm/gems/jruby-1.7.4@dm-types/gems/rspec-1.3.2/lib/spec/runner/options.rb:188: Use RbConfig instead of obsolete and deprecated Config.

This happens on spec spec/ and on rake spec.
