I figured out my problem with the subject line - it was Eclipse 4.5.2 apparently. I just downgraded to Eclipse 4.4.2, installed WOLips 4.4 and the project is working (just an annoying
little CSS issue to work out).
So, my working solution for Mac OS X 10.11.4 is:
Eclipse 4.4.2 Standard (64 bit)
WOLips 4.4 (wrong/old URL in the Learning the Wonders book)
Java 1.8
Wonder 6.1.4
Thank you all for the suggestions and assistance.
