Log Message:
Update ruby-rspec-core to 2.11.1.

### 2.11.1 / 2012-07-18
[full changelog](http://github.com/rspec/rspec-core/compare/v2.11.0...v2.11.1)

Bug fixes

* Fix the way we autoload RSpec::Matchers so that custom matchers can be
  defined before rspec-core has been configured to definitely use
  rspec-expectations. (Myron Marston)
* Fix typo in --help message printed for -e option. (Jo Liss)
* Fix ruby warnings. (Myron Marston)
* Ignore mock expectation failures when the example has already failed.
  Mock expectation failures have always been ignored in this situation,
  but due to my changes in 27059bf1 it was printing a confusing message.
  (Myron Marston).

### 2.11.0 / 2012-07-07
[full changelog](http://github.com/rspec/rspec-core/compare/v2.10.1...v2.11.0)

Enhancements

* Support multiple `--example` options. (Daniel Doubrovkine @dblock)
* Named subject e.g. `subject(:article) { Article.new }`
    * see \ 
[http://blog.davidchelimsky.net/2012/05/13/spec-smell-explicit-use-of-subject/](http://blog.davidchelimsky.net/2012/05/13/spec-smell-explicit-use-of-subject/)
      for background.
    * thanks to Bradley Schaefer for suggesting it and Avdi Grimm for almost
      suggesting it.
* `config.mock_with` and `config.expect_with` yield custom config object to a
  block if given
    * aids decoupling from rspec-core's configuation
* `include_context` and `include_examples` support a block, which gets eval'd
  in the current context (vs the nested context generated by `it_behaves_like`).
* Add `config.order = 'random'` to the `spec_helper.rb` generated by `rspec
  --init`.
* Delay the loading of DRb (Myron Marston).
* Limit monkey patching of `describe` onto just the objects that need it rather
  than every object in the system (Myron Marston).

Bug fixes

* Support alternative path separators. For example, on Windows, you can now do
  this: `rspec spec\subdir`. (Jarmo Pertman @jarmo)
* When an example raises an error and an after or around hook does as
  well, print out the hook error. Previously, the error was silenced and
  the user got no feedback about what happened. (Myron Marston)
* `--require` and `-I` are merged among different configuration sources (Andy
  Lindeman)
* Delegate to mocha methods instead of aliasing them in mocha adapter.
