The installer will first write the CGAL files and then compile the CGAL
library. Consult the CGAL installation script log file MacOSX-install.log
(can be found under the CGAL root directory) for important information
about whether the CGAL setup was successful and about environment
variables that you need to define.

The CGAL install program will try to find configure several libraries in
your system. In particular these libraries include boost, GMP/MPFR
and Qt.

Important note: boost is actually required by CGAL, which means
that the install program will fail if boost is not found.

In order for these libraries to be correctly configured with CGAL you
must make sure, before proceeding with the installation program, that
they are installed under the proper path.
You may need administrator access to setup the libraries under the
proper paths.
* boost: boost include files must be installed under /usr/include or
   /usr/local/include
* GMP/MPFR: GMP/MPFR include files must be installed under
   /usr/include or /usr/local/include. GMP/MPFR libraries must be
   installed under /usr/lib or /usr/local/lib 
* Qt: Qt files must be installed under /Developer/qt.
