I'm using the prebuilt Qt 4.2.2 release.

After installation, I needed to change QT_EDITION_UNKNOWN to 
QT_EDITION_OPENSOURCE in 
/Library/Frameworks/QtCore.framework/Headers/qconfig.h to get anything 
to compile.

Before doing --with-qtdir=/usr/local/Qt4.2 in the old build system, I 
needed to add the following links:

ln -s /usr/bin /usr/local/Qt4.2/bin
ln -s /Library/Frameworks /usr/local/Qt4.2/lib

I also changed the following link (it was set to macx-xcode):

ln -sfh macx-g++ /usr/local/Qt4.2/mkspecs/default
