Yes, there are some minor differences between the build systems for Qt 4.1
and the Qt 4.2 snapshot releases, and sipconfig needs to be taught about
them. See this message for more information:


Since only development snapshots are available for Qt 4.2, PyQt4 doesn't
yet support it. If you are enthusiastic enough to try to get them to work
together, you'll also need to make your own .sip files for the new classes,
and that these will become obsolete once PyQt4 supports them.
