Why is my Rails Thin webserver throwing a bundler error ? - Rails 3

Here is my Gemfile:

source 'http://rubygems.org'

gem 'rails', '3.0.0'

gem 'sqlite3-ruby', :require => 'sqlite3'
gem 'will_paginate', '3.0.pre2'

gem 'paperclip', :git => 'git://github.com/thoughtbot/paperclip.git'
gem 'mime-types', :require => 'mime/types'

gem 'rails3-generators'

gem 'devise',  '~> 1.1.3'
gem 'devise_invitable', '~> 0.3.4'

gem 'declarative_authorization', :git => 'git://github.com/stffn/declarative_authorization.git'

gem 'aasm'
gem 'braintree'
gem 'thumbs_up'
gem 'best_in_place'
gem "friendly_id", "~> 3.2"
gem 'aws-s3'

group :development do
    # Server
    gem 'thin'
    #gem 'rspec-rails', '2.0.1'
    gem 'annotate-models', '1.0.4'
    #gem 'rails-erd'
    gem 'annotate'
    gem 'faker', '0.3.1'
    gem 'ruby_parser'
end

group :test do
  gem 'rspec', '2.0.1'
  gem 'webrat', '0.7.1'
  #gem 'spork', '0.8.4'
  #gem 'factory_girl_rails', '1.0'
end

Here is the error I am getting:

I used to have rails_admin installed, but I commented it out and r开发者_Go百科an bundle update and bundle install.

Still getting this error though.

Delete config/initializers/rails_admin.rb, relax and float down stream.
