I don't mean add a constraint for 0.0.1.  We want rspec-support to be constrained to the same minor version as rspec-core (but with any patch level OK) -- or if it's a prerelease, to be the same version.  You don't have to release to make that work -- just update rspec-support's version constant so that it is `3.0.0.pre`, and the update the gemspec here like the `rspec` gem's gemspec.
