I've been developing an app using PyQt 4.5, Qt 4.5.1 and Python 2.5, but I recently learned that the target machine has Python 2.4 installed, along with a whole stack of dbus/avahi bindings my app needs. I'm not married to Python 2.5, but wanted to ask: can I use PyQt 4.5 with Python 2.4? Does it even work, and are there any caveats?
