first, here are my versions:
Greg-Nowickis-MacBook-Pro:sample_app Greg_Nowicki$ ruby -v
ruby 2.0.0p451 (2014-02-24 revision 45167) [x86_64-darwin13.1.0]

Changing development.rb did not help me at all.
However, what did help me is:
$ rvm 2.0.0
BEFORE creating the app with
$ rails new first_app
Note that the Gemfile version was 2.0.0, and not 2.1.1 which is what I had originally, so match the ruby versions before you create your app.
Not sure why this is important.
Try using a different version of rspec by replacing the beta version with this version in your Gemfile: gem 'rspec-rails', '>= 2.14'
EDIT: Have you run bundle install
and rails generate rspec:install
before trying to run rspec?
In config/environments/development.rb:
change
Rails.application.configure do
to
SampleApp::Application.configure do
I checked a couple of my applications, and thats the format I have them.
