I decided to run a bundle update on one of my core projects today and lo and behold, I received the following error:

Gem files will remain installed in /Users/kelvin/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/therubyracer-0.12.2 for inspection.

Unfortunately, there’s not an easy way to directly link to the download but here’s the link to the general Developer Downloads from Apple
