=> Ctrl-C to shutdown server

Приведи содержание config/environment.rb ,
config/environments/development.rb

Кроме прочего,
1. Лучше указать в Gemfile: gem 'rails', '~> 4.0.2'
для использования последней 4.0.x версии RoR. В следующих версиях после 4.0.2 были исправлены различные ошибки и недочёты.
3. Запускать "bundle exec rails s"

Answer 1

[ТыжСисАдмин]

gem install rails

Answer 2

[Viktor Vsk]

rbenv rehash
bundle exec rails s
rm -rf ./bin && bundle exec rake rails:update:bin

Вообще, гадать в таком ограниченном количестве информации сложно.
Прямая ошибка ведет сюда

Плюс, просто гуглите

undefined method `configure' for # (NoMethodError)
