`gem install therubyracer` fails on Mac OS X Lion

Question

I would appreciate some help in getting gem install therubyracer to work. Here is the error:

$ gem install therubyracer
Building native extensio

If you need 0.11.3 and it's failing give this a shot for Mac OS X 10.9...

gem uninstall libv8
brew install v8
gem install libv8 -- --with-system-v8
gem install therubyracer -v '0.11.3' -- --with-system-v8

See this issue for more details.

You probably don't need the -- --with-system-v8 on the last line but I did it just to be safe since I saw it start doing Fetching: libv8-3.11.8.17-x86_64-darwin-13.gem (1%) when I ran the command...

Anyhow, it worked for me when all the other things did not.
