It could be that rubygems is fetching the wrong binaries for your system.

Diagnosis:

• Compare the output of gem env platform to 'Kernel Version' under  > About This Mac > System Report > Software
• If those don't match (e.g. Kernel Version: 14.4.0 and x86_64-darwin-12) then RubyGems is grabbing the wrong version of therubyracer and libv8 for your system

Fix:

• short-term: bundle update therubyracer --platform=x86_64-darwin-14
