One of our illustrious users (Răzvan Popa) discovered an issue with the dse-driver gem that basically made it DOA for MRI. Further investigation proved we have an issue for JRuby as well.
We've resolved the issue (
RUBY-253) and are releasing v1.0.1 today -- it's a patch release with only this fix on top of 1.0.0. Also, we've removed 1.0.0 from RubyGems since it's DOA.
Thanks for your patience, and let us know if you run into any issues.
