To Reproduce Steps to reproduce the behaviour:

Check out the latest version of master.
npm install
gulp

Additional Notes If you disable the lint step in the gulp file, it does build & run ok (sort of).

Looking at the lines in the file it is referring to, for the first one in the file at-least, the options object hasn't been initialised at the point you are setting a value inside it; is it just a case of initialising it first, or was a pre-filled object supposed to be passed?
