Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/do_postgres-0.10.14 for inspection.
Results logged to /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-13/2.0.0/do_postgres-0.10.14/gem_make.out
An error occurred while installing do_postgres (0.10.14), and Bundler cannot continue.
Make sure that `gem install do_postgres -v '0.10.14'` succeeds before bundling. 

My Gemfile contains this:

source 'https://rubygems.org'
ruby '2.0.0'
gem "sinatra"
gem "sinatra-contrib"
gem "sinatra-flash"
gem "thin"
gem 'data_mapper'
gem 'omniauth'
gem 'omniauth-google-oauth2'
gem 'omniauth-github'
gem 'sass'
group :development do
 gem 'dm-sqlite-adapter'
 gem 'do_sqlite3'
end
group :production do
 gem 'pg'
 gem 'dm-postgres-adapter' 
end

I have tried installing postgres manually and I have it installed on my computer but it keeps failing. I am running Mac OSX Mavericks

• Beed: If you are just trying to get started developing and don't need postgres as your database, you can run "bundle install --without production". This will cause bundler to ignore the pg gem.

Try installing postgres with homebrew. http://www.moncefbelyamani.com/how-to-install-postgresql-on-a-mac-with-homebrew-and-lunchy/

• Nestoraj: It work!! Thanks you so much, I've been trying this a long time
