Nevertheless, you have installed in /Library/Frameworks/ a 32 bits version of 
Qt, whereas your default architecture is 64 bits.

It should be doable, even on a 64 bits system, but you would need to install 
32 bits version of all dependencies of CGAL. In my opinion, you should avoid 
doing so.

You should install the 64 bits version of Qt.

The CGAL_Qt4 library is needed only by some CGAL demos, but not by the CGAL 
library itself. You can configure CGAL with WITH_CGAL_Qt4=OFF, so that the 
compilation process does not try to compile CGAL_Qt4.
