I've updated Qt to 4.4.0 (release). it builds for me on nv83 amd64, not tested in anything else (like, say, S10U4 or on SPARC). You must uninstall the existing Qt before compiling Qt 4.4.0 because it picks up the existing headers and libs otherwise (this is because our Qt lives in /opt/foss, alongside some of its dependencies).
