Comment(by mmoll@…):

 I need to change the compiler to this: {{{ configure.compiler llvm-gcc-4.2
 }}} with raphael's patch to comple the demos variant. Even then, some of
 the demos are broken, because they expect plugins to be installed in
 /opt/local/lib. For example, this is what happens for me:
 {{{
 /opt/local/share/cgal/demo/Surface_reconstruction_points_3/Point_set_demo
 dyld: Library not loaded: /opt/local/lib/libPS_demo_scene_item.dylib
   Referenced from:
 /opt/local/share/cgal/demo/Surface_reconstruction_points_3/Point_set_demo
   Reason: image not found
 Trace/BPT trap: 5
 }}}
 Patching the CMakeLists file is probably the right way to go, but that's a
 pain. You can probably fix the programs without plugins using the attached
 patch for CGAL_CreateSingleSourceCGALProgram.cmake (untested). Perhaps the
 demos with plugins can be disabled?
