If you want to avoid using MacPorts, you can download the Postgres App and place it into the Application directory.
Then, specify the location of newly downloaded pg_config
:
gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/latest/bin/pg_config
If you run in to missing headers problem, try specifying the include
directory of the app:
gem install pg -- --with-pg-include="/Applications/Postgres.app/Contents/Versions/latest/include/"
