Here is where my adventure starts
Bug 1: In windows, after installation you must set full permissions of the install dir for anyone wishing to invoke qmake.
Bug 2: Rather than invoking qmake as explained in most tutorials, Mac users must invoke qmake -spec macx-g++
Bug 3: QtWebKit requires you to manually edit the Makefile generated by the bug2 command.... perhaps you need to do more with -spec
figuring out these issues took me 2 nights work (interrupted by a couple hours of TV of course), I hope I saved you that time.
