Setting up vm

When trying to setup the `vm`, getting an error stating that `~/.mason` has not been setup:
```
$ mason stacks:create lucid64
* creating stack lucid64...   ! No such file or directory - /home/daithi/.mason/Vagrantfile
```

Solution is to install a buildpack first:
```
$ mason buildpacks:install https://github.com/heroku/heroku-buildpack-python
.git
* installing buildpack https://github.com/heroku/heroku-buildpack-python.git
```
