ruby-on-rails Heroku deployment crash

This is the message I get from Heroku:

Application Error An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details.

Here are my Heroku logs:

Would someone mind explaining what this means? It runs perfectly fine locally on my computer. Thanks.

EDIT:Gemfile

source 'https://rubygems.org'

gem 'rails', '3.2.12'

gem 'devise'
gem 'simple_form'
gem 'state_machine'
gem 'draper', '~> 1.0'
gem 'js-routes'
gem 'paperclip'
gem 'will_paginate'
gem 'bootstrap-will_paginate'

group :development do
  gem 'thin'
end

group :test do
  gem 'shoulda'
  gem 'factory_girl_rails'
end

group :development, :test do
    gem 'sqlite3'
  gem 'log_buddy'
end

group :production do
    gem "pg"
end

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

Problem 2: after thin gem removal. Heroku Logs:

Sure, you don't have thin in your prod gemset

Take the group :development out from around the gem thin line.

Heroku isn't downloading a gem (thin) needed to be your webserver

EDIT

The key line in troublshooting from all that log output is

app[web.1]: bundler: command not found: thin

That means that bundler is trying to boot up your app, but doesn't know about something called thin. How do you 'teach' your app about new things? The gemfile. That's the thought process I ran through.

Heroku always sets RAILS_ENV to :production by default, which will only install gems from the default or production gemsets. That was the core issue here.
