Great idea, but oh the irony - it's currently throwing a Bundler::GemNotFound exception.
Could not find gem 'remarkable_activerecord (= 4.0.0.alpha4, runtime)' in any of the gem sources. ()
EDIT: back up almost immediately.
Sorry about that. We're seeing intermittent issues with our Passenger installation. And we're currently upgrading the machine... we should be more stable, in a few minutes.
