Install your OS specific version of VirtualBox:
https://www.virtualbox.org/wiki/Downloads
N.B. The VirtualBox version in apt-get or yum repositories is usually very out of date.
Install Vagrant:
http://www.vagrantup.com/downloads.html
N.B. The Vagrant version in apt-get or yum repositories is usually very out of date. Current version at the time of writing this is 1.6.3.
Install Vagrant-Cachier at the console:
vagrant plugin install vagrant-cachier
If you have all the OS dependencies install from above, just run from the directory where you cloned this project into:
vagrant up
You will see it will hang when trying to install the meager amount of dependencies when using the shared dir /var/cache/pip.
