The most current version of Luma is only working with
PyQt3. Support for PyQt4 is planned (see Roadmap) -
but since qt3widgets is not a part of pyqt4, porting will
take more time than we would like. The positive side
is that Luma will be _only_ PyQt4 with no back-bindings
to qt3.
Luma has been reported to work with Python versions 2.3 and 2.4.
It might as well work with 2.5 - but we don't have a test-bench
with python 2.5 available.
