Answer 1

Tertom's solution posted on github solved it for me, after having tried all other solutions proposed on the respective github issue and here.
I had the exact same system configuration.
This is on el capitan, so not an exact answer to the question, but people might find this info helpful.

I'm citing it here for visibility:

Solved the same problem

• MacOS 10.11.2
• ruby 1.9.3
• libv8 3.16.14.13
• therubyracer 0.12.2

--

brew tap homebrew/versions  
brew install v8-315  
brew link --force v8-315  
bundle install  
brew unlink v8-315

If you also cannot install libv8,

gem install libv8 --with-system-v8

or

bundle config build.libv8 --with-system-v8
