This basically means that you're missing a library or program on your setup. I've had this issue a couple of times now so here are a few different things to try (hopefully one of them will work for you):

Install a common missing library:

brew install libpqxx
gem install pg

Reinstall postgres (not ideal I know):

brew uninstall postgresql
brew install postgresql
gem install pg

Explicitly define path of pg_config:

1) Get location of pg_config

which pg_config

2) pass that path into gem install

gem install pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config

Try this it will work

sudo apt-get install -y libpq-dev build-essential postgresql-server-dev-all libpgsql-ruby postgresql ruby-dev && gem install pg
