I found a different version of a script that does essentially the same thing, but it's a little more robust, and it works perfectly. Here it is:

i believe my problem with the other script was the order of the list of Qt Frameworks to embed. I always put QtCore first, and this script it written to search for the dependencies and include them in that order, and QtCore seems to come up last, and QtXml first. I won't bother trying the other one again, because this one is a better script all around anyways.
