Install postgres on osx mavericks - ruby-on-rails

Question

I have the postrgres application installed in Mavericks. It's running on port 5432.
I have a rails project which uses the pg gem.
However, when running "bundle install" I get this error:
Installing pg (0.17.1)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
/Users/jonathanhurley/.rvm/rubies/ruby-2.0.0-p247/bin/ruby extconf.rb

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

Could not create Makefile due to some reason, probably lack of necessary

need configuration options.

Gem files will remain installed in /Users/jonathanhurley/.rvm/gems/ruby-2.0.0-p247/gems/pg-0.17.1 for inspection.
Results logged to /Users/jonathanhurley/.rvm/gems/ruby-2.0.0-p247/gems/pg-0.17.1/ext/gem_make.out
An error occurred while installing pg (0.17.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.
I'd understand this error if postgres wasn't installed but it is.

I recommend installing Homebrew first, as it's a great package manager for OS X. You can install it with this command:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
After you get homebrew installed, you can then install postgresql with your brew command.
brew install postgresql
My coworker had the same issue you had yesterday, but after installing again with homebrew, it works as intended.
