Handlebars precompile version error with Ember rc1-Collection of common programming errors

This was caused by barber gem which is using handlebars rc2 for template precompilation. I’ve made a pull request which fixes it. If you need this working now, you can just use my fork 🙂

Update: instructions for using darthdeus fork:

1) Add the following to your Gemfile:

gem "barber", :git => "git://github.com/darthdeus/barber.git", :branch => "update-handlebars-to-rc3"

2) Clear your tmp dir

rm -rf tmp

3) Restart your server

edit: for future readers the changes have been merged now, so using a master branch from the official repo should work.
