My commit is not guaranted to work as i was unable to test it. We'll need some 
refining. Sure. But it is the way to go.

Yes, it seems like there is an include path missing. Normally Qt adds two 
include paths for each module: the QtGui one and the upper so that this 
should work. Let's see what macports pkgconfig does.

I guess analog content. Changing at least the module name and maybe some few 
options :-)

Of course. I just changed the scons to use the same code for mac than we used 
for linux. What it does is to populate the compilation options with the ones 
provided by the pkg-config files for each qt modules we enable. Previous code 
added such options by hand and had two codes we switched on and off depending 
on whether they used frameworks or not. By relying on pkg-config, we don't

Note this very last line it includes /opt/local/include/qt4-mac and 
${includedir} which is defined above as ${prefix}/include/qt4-mac/QtGui being 
prefix /opt/local.

So both -I/opt/local/include/qt4-mac and -I/opt/local/include/qt4-mac/QtGui 
options should be included and that should work.

To assure this point, please compile the NetworkEditor (or the qt app you are 
trying to compile) with a 'verbose=1' flag. This will display the command 
line options used to compile each file. Paste one of those lines to the list.

Just in case check: In order to use the new qt4.py tool you need to do an 
scons install of the CLAM libraries.

For a later phase check also that QtOpenGL.pc includes options to link with 
OpenGl framework. If not we should add them in qt4.py
