This is a constraint induced by Maya then.

Well, in theory, all versions of PyQt4 should work with all versions of 
Qt4.

If you depend on a Qt feature that appeared in a certain version, this 
feature 
is available only, if PyQt4 is adapted to that feature and is compiled 
against a Qt version containing that feature. This is possible due to 
sips 
timeline feature and a complex version dependency scheme.  

In practise, you determine the lowest Qt version that you need to 
support, and 
build the newest sip/PyQt4 against it. Keep in mind, that sip/PyQt4 
depends 
on the particular Python revision, it is build with. I cannot say 
anything 
about Mayas PyQt bindings, though.
