Is this something about my Ruby install?

Hi Sam,

Sorry for the confusion, and I apologize for the inconvenience. The currently released gem version of libv8 does not compile properly on ubuntu, but has since been fixed with cowboyd/libv8@cf58d33a830259f5749b129ab6d5282d4ee1a8e1. I would try installing both libv8 and therubyracer from master. Here is a sample Gemfile that should accomplish what you need:

source 'https://rubygems.org'

gem 'libv8', git: 'https://github.com/cowboyd/libv8.git', submodules: true
gem 'therubyracer', git: 'https://github.com/cowboyd/therubyracer.git'

Note the submodules: true option. This is necessary, because it needs to pull in and compile the v8 source from v8/v8 as a submodule.

We are in the process of pushing out a newer version of libv8 with binary versions for most major platforms, including linux-x64. I hope this helps, and I'm sorry for the delays.

I've now released libv8 3.16.14.2 which contains these fixes.
