Use Cask to trigger tests (and solve dependencies)

Follow up from the discussion #370 (comment)

Use:
- Install Cask -
http://cask.readthedocs.org/en/latest/guide/installation.html
```sh
curl -fsSL https://raw.githubusercontent.com/cask/cask/master/go |
python
```
- Trigger tests:
```
make check
```
This will use cask only for the tests target.
