Hello, update: I was using ruby version manager as suggested in several blog posts. It actually worked fine till now. Since I was encountering those problems with rails 3, I decided to try the process in my system ruby, ruby enterprise 1.8.7 and it seems to work well so far. Both with sqlite and postgres. Thanks a lot! Luca B.
