Comment(by russell.jones@…):

 I have the same problem. The build seems to be failing at
 {{{

 This is present in all the files.

 This post looks relevant: http://cgal-

 There is bug in the Qt4 moc tool, that makes it incompatible with some
 Boost
 files from Boost-1.48.

 In CGAL-4.0-beta1, we have introduced a workaround. Copy the following
 lines
 near the beginning of CGAL-3.9/include/CGAL/config.h, if you want to fix
 that
 bug keeping CGAL-3.9:


 // Workaround to the following bug:
 //   https://bugreports.qt.nokia.com/browse/QTBUG-22829
 #ifdef Q_MOC_RUN
 // When Qt moc runs on CGAL files, do not process
 // <boost/type_traits/has_operator.hpp>
 #  define BOOST_TT_HAS_OPERATOR_HPP_INCLUDED
 #endif


 I am not really proud of that workaround of mines, but at least it works.
 }}}

 I can have a go at creating a patch/portfile, but not until next
 Wednesday.
