are you sure that you installed g++ and not just g++-X.Y ?

You can copy /usr/share/cgal/makefile, edit CGAL_CXX and point CGAL_MAKEFILE 
to
that copy. But I doubt that g++-3.3 is the default compiler on Ubuntu feisty,
hence, linking will most probably fail.

As already pointed out to you, you should rather install the g++ package, 
which
depends on the correct g++-X.Y package (the default compiler, which was used 
to
compile the CGAL libraries).

Note that I am not familiar with Ubuntu, I'm just guessing based on my Debian
experience. Maybe it is better to ask in some Ubuntu-related forum.
