Я только что установил PostgreSQL 9.x на мой Mac и при попытке запустить bundle install после добавления pg в мой gemfile я получаю:

Подсказка находится в:

No pg_config... trying anyway. If building fails, please try again with --with-pg-config=/path/to/pg_config

Вам нужно указать его на файл pg_config.

Итак, найдите, где находится файл pg_config, и запустите:

gem install pg --with-pg-config=/path/to/pg_config

...
