libv8-3.16.14.3 Fails to install - Rails 4.1.8

So I have this issue where libv8-3.16.14.3 fails to install, even though it deceptively tells you it did install.

So the first sign of issue was when it did:

An error occurred while installing libv8 (3.16.14.3), and Bundler cannot continue.
Make sure that `gem install libv8 -v '3.16.14.3'` succeeds before bundling.

During a bundle install. So I did some googling and came across this response which when run:

gem install libv8 -v '3.16.14.3' -- --with-system-v8
Building native extensions with: '--with-system-v8'
This could take a while...
Successfully installed libv8-3.16.14.3
Parsing documentation for libv8-3.16.14.3
Done installing documentation for libv8 after 1 seconds
1 gem installed

Leads you to thinking it worked. but run bundle install again and see the error in question which is:

An error occurred while installing libv8 (3.16.14.3), and Bundler cannot continue.
Make sure that `gem install libv8 -v '3.16.14.3'` succeeds before bundling.

The entire trace log can be seen below (caused by running bundle install):

This error is common with projects with therubyracer and the other answers didn't solve it for me. They helped though. Order of install seem to be the clue.

$ gem uninstall libv8
Successfully uninstalled libv8-3.16.14.13
$ gem install therubyracer -v '0.12.2'
2 gems installed
$ bundle
CRASH
$ gem install libv8 -v '3.16.14.13' -- --with-system-v8
Successfully installed libv8-3.16.14.13
1 gem installed
$ bundle
SUKSESS

go figure, this is bad. But it solved it for me.

I got this to work by first using Homebrew to install V8:

$ brew install v8

Then running the command you mentioned you found on Google:

$ gem install libv8 -v '3.16.14.3' -- --with-system-v8

And finally re-running bundle install:

$ bundle install
