Serghei,

   After building qt3 in a pristine build environment, I thought I would build 
the rest of trinity there while I had the chance. So far, the dependencies have 
built without issue:

trinity-qt3-3.3.8c-1-x86_64.pkg.tar.xz
trinity-pyqt3-3.18.1-9-x86_64.pkg.tar.xz
(poppler-qt3 still fails)
trinity-dbus-1-qt3-0.9-7.2-x86_64.pkg.tar.xz
trinity-tqtinterface-1230411-1-x86_64.pkg.tar.xz

   Building arts, I have run into another .moc file that isn't generated. This 
time it is qiomanager_p.moc. The build gets to 100% and then dies with:

   Checking the build directory -- no qiomanager_p.moc was every generated. 
Could you take a look and see if this is like the kdevelop issue :)
