This error happens whenever the qt include path is not added to the moc 
command or the QTDIR var is not properly defined.

The recommended procedure is to install the mac native version of Qt compiled 
as framework which is the one the qt4.py scons tool supports in mac. Andreas 
did an spike on using macports but we decided to abandon it by now. If you do 
so, qt will be installed into /usr/local/Trolltech/Qt-X.X.X being X.X.X the 
version. If you set the QTDIR environment var to that path all should work
