Can't reproduce.

Scratch builts for both FC12 and FC13 don't fail:
FC13: http://koji.fedoraproject.org/koji/taskinfo?taskID=1818717
FC12: http://koji.fedoraproject.org/koji/taskinfo?taskID=1818674

I don't know what the actual cause for your build-breakdowns was, however, based on what I see in your build.logs, I am inclined to think your built might have picked up a broken version of qt.

using  qt-devel-4.6.0-0.5.beta1.fc13.  

cd /builddir/build/BUILD/OpenSceneGraph-2.8.2/BUILD/examples/osgviewerQT && /usr/bin/c++   -DOSG_DEBUG_POSTFIX=d -DUSE_QT4 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_

/usr/include/QtGui/qgesturerecognizer.h:45:21: error: qglobal.h: No such file or directory

now qglobal.h is present in 2 places:
$rpm -qpl qt-devel-4.6.0-0.5.beta1.fc13.i686.rpm | grep qglobal
/usr/include/Qt/qglobal.h
/usr/include/QtCore/qglobal.h

but I don't see -I/usr/include/Qt/   or similar construct.    That could do it.

That would definitely do it.

http://qt.gitorious.org/qt/qt/commit/f93ade8e1976ea605fe78c4c663ff8f8fa41d323

was when that hit mainline, and you picked it up due to the Qt bump.  OK, this can stay closed then. :-)
