I feel that kind of information should be in the Docs and in the Reader on Github; especially if the future is Bundler
No. 0.5.5 uses an old version (pre 2.0) of rspec. The master branch on github uses modern versions of rspec, unfortunately it's note quite ready for a release yet, though it's getting close.
You're right. The dependencies ought to be documented. We'll try to make that happen in the upcoming release.
