the problem is in mac's frameworks. I will try to explain it on QtCore case.

They are storing includes in
/Library/Frameworks/QtCore.framework/Headers

so the original qt_includes.h containing

#include <QtCore/QtCore>

fails because it cannot find a file to include. It must be used as

#include <QtCore>

Using Q_OS_MAC is not a solution too because macports version of qt4 is using 
its "unix" location in e.g. /opt/local/share/include/QtCore/QtCore

And there is no definition of QT_USING_FRAMEWORKS or something similar in qt4 
itself. And never will be (qt4 crew asked already).

but maybe the qt_includes.h can be changed to contain <QtCore> only (not 
<QtCore/QtCore> it should work too because we have -I/usr/include/QtCore/ in 
gcc args too (do we?) - but I did not test it - it's just a quick idea. And I 
cannot test it now. Have to wait until Monday.
