When I run bundle install I get
bundle install
An error occurred while installing libv8 (3.11.8.17), and Bundler cannot continue. Make sure that `gem install libv8
You can actually install that version on Mavericks:
gem install libv8 -v 3.11.8.17 -- --with-system-v8
I can confirm this works with rbenv and ruby 1.9.3p448
