RoR - Failed to installing pg on rails app

I'm trying to push a project to heroku....

I'm at the step where it say's: rails new myapp --database=postgresql

After I created the command: rails new heroku:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing pg (0.17.0), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.0'` succeeds before bundling.

On my MacBook(Mac OS X Mavericks) I get the error:

$ gem install pg

Install Postgres

brew install postgresql

Then your gem install pg would work, it is failing because it needs the postgresql-client to work
