Back-end unit tests failing on local install

[jbonacci]

Performed a simple, local install to my Mac.
Ran the back-end unit tests with the following command:
npm test

Failed at this point in the tests:
tests/verifier-test.js
The "sys" module is now called "util". It should have a similar interface.

yes, known heisenbug, ignore for now :)

Odd. Same simple install to Ubuntu works (same node and npm).
