This exact thing happened to me last year, too. Though in my case I was already between gigs so it wasn't as big a deal.

Look at it this way -- would you really want to work at a company that would rescind a job offer this way? It says a lot about a company that they don't have their act together enough to know if they can hire or not.

Good RoR devs are hard to find -- I'd just let your current employer know what happened and see if they'll keep you on. Just say that the offer they made was too good to refuse. And, as it turned out, was too good to be true in the end.
