Hate to say it, but for now you have to uninstall the offending version  
of i18n (specifically 0.5.0 with ‘gem uninstall i18n’) Then ‘gem install  
rails’ to get the proper version

It’s an issue with Mail’s dependencies being too tight - and it only  
seems to be an issue when Bundler isn’t being used (or particular  
versions of Bundler?)

We’ve asked Mikel to quickly relax the dependencies. I haven’t received  
any answer to today’s messages and will have to pull/yank the release in  
case he’s busy or can’t do a Mail release.

I’m very sorry about this, but it’s something that - because of the way  
bundler works - wasn’t visible to me before 0.5.0 was out of the door  
(and someone used `rails new`). We’ve all thought Mail would have  
relaxed its dependencies weeks ago, but apparently something has gone  
wrong with that.

Apparently it’s fixed now

Please update your Mail gem

$ gem update mail

Afterwards

$ rails new foo

should work again.

Could someone doublecheck? It’s getting late over here 🙂
