What I'm about to tell you is used internally, is not a formal API, and is subject to change without notice. That said, for the moment, you can do this:
# ... load rails
rspec spec --tag no_rails
I created https://github.com/rspec/rspec-core/issues/416 to address formalizing an API for this. Comments/suggestions/patches welcome.
