Last doc on Wheezy need a Debian package

Created by: ymsaout

I had a problem to make this command on debian install on Wheezy :

sudo -u git -H bundle install --deployment --without development test postgres aws

with this message :

An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue. Make sure that gem install mysql2 -v '0.3.11' succeeds before bundling.

Fixed with :

apt-get install libmysql-ruby libmysqlclient-dev
