You need a minimum of Qt-4.3.0. I suggest getting the latest.
__Snow Leopard note:__ If you are building on Snow Leopard, you will need to
decide between 32-bit support in the older, Qt Carbon branch, or 64-bit
support in the Qt Cocoa branch. Appropriate installers are available for both
as of Qt-4.5.2, and the release candidate of Qt-4.6.0-cocoa works fairly well
with Qgis as tested with nightly snapshots of sip and pyqt.
Unfortunately, the 32-bit branch of Qt currently does not build using cmake with
python bindings. You can achieve support for python in Qgis with
the Xcode build method noted below.
