There's a teensy issue in stdcxx 4.1.3 that triggers a bug / weakness in Qt's moc parser. I've added a patch to stdcxx for that, so you should rebuild. Or save yourself hours and hours of compiling and edit /opt/foss/include/loc/_facet.h and add a ; to the line with _USING so it reads
_USING(namespace std;); I have removed all the hacks in the kde build that work around that missing ; , so this *is* a necessary fix update. [ade]
