Yes, Tk 8.5 isn't quite compatible with existing Tkinter code; there have been a lot of changes which break Tkinter applications (though not Tkinter itself). OTOH, it's more likely that the PIL binaries you are using conflict with your Tk installation - if the binaries were for Tk 8.4 (which isn't quite clear to me whether that's indeed the case), then they can't work with Tk 8.5, as Tk doesn't provide that kind of binary compatibility.
