php-qt builds against qt 4.1.0-r2 on amd64 system (k8) and the examples work ok :)
Also the third release is out: "2006-06-08 The third release of PHP-Qt is now available. It contains the first 7 tutorials and an example application. Custom Slots/Signals and a better error- and argument handling were implemented and the implementation of all classes are generated with kalyptus. See Changelog for more details."
Done.
