I thought this looked familiar.  In rebuilding Qt today, therefore  
looking at my Qt notes, I found my note about this - Some (many?  
all?) of the headers in Qt assume a normal unix bin/lib/include  
structure, so the includes in the frameworks are not found.  So,  
#include <QtCore/qnamespace.h> looks in QTDIR/include/QtCore/, which  
doesn't exist.

Normally the framework mechanism takes care of this so <QtCore/ 
qnamespace.h> would get translated into QTDIR/lib/QtCore.framework/ 
Headers/qnamespace.h, but that doesn't seem to be happening with  
QGIS.  It needs the -F [dir] option to work, similar to the -I option  
for normal includes.  dir is the folder containing the frameworks,  
QTDIR/lib.  So maybe QGIS isn't adding this on a Mac build (I haven't  
got to Qgis yet today).

My quick-n-dirty solution was to add symlinks in QTDIR/include to the  
framework Headers folders:

include/QtCore -> ../lib/QtCore.framework/Headers
...
