Eu fiz primeiramente um git clone e segui os passos indicados para a instação da aplicação com o boostrap. Como não funcionou, levantei a hipotese de ter feito algo errado, e fui refazer os passos do zero.
Só que agora quando dou 'bundle install', retorna o seguinte erro:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Alguma idéia?
