Hi,

I am new to Rails and am following Rails tutorials by Michael Hartl and 
Rails guides. I have deployed an app to Heroku, but I get this error while 
trying to access it (from heroku logs) - 

Completed 500 Internal Server Error in 79ms 
<%= stylesheet_link_tag    "application", :media => "all" %>
ActionView::Template::Error (application.css isn't precompiled)

I want to use Twitter Bootstrap and have followed the instructions 
mentioned here - https://github.com/seyhunak/twitter-bootstrap-rails
The contents of my Gemfile are -

gem 'rails', '3.2.1'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :development, :test do
  gem 'sqlite3'
  gem 'heroku'
  gem 'rspec-rails'
  gem 'twitter-bootstrap-rails'
  gem 'annotate', '~> 2.4.1.beta1'
end

group :test do
  gem 'webrat', '0.7.1'
end

group :production do
  gem 'pg'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported 
runtimes
  gem 'therubyracer'

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

The thing I don't understand is that there are no bootstrap related css or 
js files in /vendor/assets /javascripts or /stylesheets folder.
I see bootstrap.js.coffee and bootstrap.css.less in /app/assets 
/javascripts and /stylesheets folders respectively.

I also added the below code to my /config/application.rb file -
# precompile 
config.assets.precompile += %w( bootstrap.css )
config.assets.precompile += %w( application.css )

My app works fine on my dev machine, but I get the above error after 
deployment to Heroku.

Please let me know what I am missing.

Thanks,
Manoj.
