Is this a Rails-3 project? Are you using the time that rspec displays, or measuring that yourself (including load times before the spec run starts)?

That warning would only happen if something was trying to reference the Spec module instead of RSpec. Feel free to open an issue for this so we can track it, but I'm pretty sure it's not anything RSpec can fix.

Thanks for the feedback!
