Hello, 

I am having some issues compiling an example from Surface reconstruction 

part. It'd be great if someone can point out what could be the issue. 

I am using Mac OS 10.8 and cgal 4.4

dn525jo5:poisson_rec hardik$ port list cgal

Warning: port definitions are more than two weeks old, consider updating them by running 'port selfupdate'.

cgal                           @4.4            gis/cgal

Compiling error: 

/usr/local/soft/UM++/hardik/3Dexamples/FromTrianles/brain/cowBrainModel/poisson_rec/poisson_reconstruction_withUMesh.cpp:64:21: error: no matching member function for call

Excerpt from the .cpp

  PointList points;

    std::ifstream stream("data/kitten.xyz");

    if (!stream ||

        !CGAL::read_xyz_points_and_normals(

                              stream,

                              std::back_inserter(points),

                              CGAL::make_normal_of_point_with_normal_pmap(PointList::value_type())))

    {

      std::cerr << "Error: cannot read file data/kitten.xyz" << std::endl;

      return EXIT_FAILURE;

    }

    // Creates implicit function from the read points using the default solver.

    // Note: this method requires an iterator over points

    // + property maps to access each point's position and normal.

    // The position property map can be omitted here as we use iterators over Point_3 elements.

    Poisson_reconstruction_function function(points.begin(), points.end(),

                                             CGAL::make_normal_of_point_with_normal_pmap(PointList::value_type()) );

    // Computes the Poisson indicator function f()

    // at each vertex of the triangulation.

    if ( ! function.compute_implicit_function() ) 

      return EXIT_FAILURE;

Thanks!
