I want to update my application to use Rails 4.2.1, so I update this line in my gemfile:
gem 'rails', '4.2.1'
When I then run bundle update I get the following error:

Doing some searching I tried the following command:
gem install libv8 -v '3.16.14.8' -- --with-system-v8 - which succeeds, but then when I try bundle update again, therubyracer fails to resolve v8 as I don't think the system has a v8 installed.
How can I resolve this libv8 issue?
The problem was because of a problem in the libv8 source : https://github.com/cowboyd/libv8/issues/174
It was fixed by installing '3.16.14.7' like this:
gem install libv8 -v '3.16.14.7'
And that passed, so then adding this to the gemfile:
gem 'libv8', '3.16.14.7'
