Please relax the Rspec dependency to allow Rspec 3+

[monfresh]

Hi,

I'm using rspec-rails 3.1.0 in my project, but since the latest version of sms-spec only allows Rspec versions less than 3.0, I can't upgrade sms-spec from version 0.1.7 to 0.1.10.

Is there a particular reason why sms-spec is not allowing Rspec 3+?

I just ran into the same thing:

Bundler could not find compatible versions for gem "rspec-mocks":
  In Gemfile:
    sms-spec (~> 0.1.10) ruby depends on
      rspec (~> 2.11) ruby depends on
        rspec-mocks (~> 2.11.0) ruby

    rspec-rails (>= 3.0.0) ruby depends on
      rspec-mocks (3.1.0)
