Function signatures with automatic tuple-unpacking are no longer allowed in
Python3. So functions or methods like this:

def moveToPoint(self,(x,y)):

have to be re-written with the tuple unpacking moved into the body of the
function, e.g. something like this:

def moveToPoint(self, x_y):
    x, y = x_y


Are you aware that you're trying to install a Python2 library under Python3?
