I was able to get this resolved, and pushed the changes to billyearney-
skulpt.
In summary, I removed the window.addEvent.. and replaced it with
window.onload, and removed the requirement for
mootools. Added in some goog.requires and added base.js and deps.js
directly in a script tag. Making these changes allowed the
tests to run, with a few unit test failures, but the majority seem to
work.
