Qt Mobility fails to build with DBus but without bluez

The bluetooth connectivity code fails to build if the following conditions are simultaneously met:

• the platform is NOT symbian
• Qt is built with dbus enabled
• bluez is NOT available

The error is:

:info:build /usr/bin/g+-4.2 -c -pipe -O2 -arch i386 -fvisibility=hidden -fvisibility-inlines-hidden -Wall -W -fPIC -DQT_SHARED -DQTM_PLUGIN_PATH=\"/opt/local/share/qt4/plugins\" -DQT_BUILD_CONNECTIVITY_LIB -DQT_MAKEDLL -DQT_NO_DEBUG -DQT_CORE_LIB -I/opt/local/share/qt4/mkspecs/macx-g+ -I. -I../../build/Release/QtConnectivity/moc -I../global -Infc -Ibluetooth -I.. -I/opt/local/include/QtNetwork -I/opt/local/include/QtCore -I/opt/local/include -o ../../build/Release/QtConnectivity/qbluetoothlocaldevice.o bluetooth/qbluetoothlocaldevice.cpp

:info:build bluetooth/qbluetoothlocaldevice_p.h:58:24: error: QDBusMessage: No such file or directory

The reason is that the dbus code is enabled as long as "QT_NO_DBUS" is not defined, but "QT *= dbus" is only active if both dbus AND bluez are found (see connectivity/bluetooth/bluetooth.pri).
