Hello!

   There is no "Triangulation::new_vertex()” method - and the 
"Triangulation::new_vertex(const Point & p)", while present in the 
“Triangulation.h” file, does not seem to be documented in CGAL’s manual. To 
add a vertex without a point, you have to access directly the triangulation 
data structure, using “YourTriangulation.tds()”. This should do the trick:

   VertexHandle vertex = YourTriangulation.tds().new_vertex();

Hope this helps.
Thiago
