Trouble deploying a Sinatra application on Heroku

Question

I am new to the Ruby and Heroku world and I am trying to deploy a very basic Sinatra app on heroku. I have the following files:

config.ru:

require './hi'
run Sinatra::Application

hi.rb:

require 'rubygems'
require 'sinatra'

get '/' do
  "Hello from Sinatra on Heroku!"
end

.gems

sinatra

When push to heroku and launch the app it crashes with the following entry in the logs:

Any help would be appreciated.

Problem was sinatra - they updated it, so now everything running smoothly on 1.2.6.
