Você não deve usar o Rails 3.0.0
Solução
excluir gemset antigo
rvm gemset delete <gemset-name>
crie um novo gemset e use-o
rvm gemset create <gemset-name>
rvm gemset use <gemset-name>
Você pode instalar a versão mais recente dos trilhos. Em 5 de março de 2014, é 4.0.3.
Se você quiser ficar com a versão 3, é necessário instalar a versão mais recente, que é 3.2.17 . faça isso executando este comando
gem install rails -v=3.2.17
