No, it makes sense. The g++ package is kind of a meta package that
depends on the default g++-X.Y package and contains /usr/bin/g++, which
is a symbolic link to the default g++-X.Y binary. If you just want g++,
install g++; if you want a specific g++-X.Y, install g++-X.Y. Simple,
isn't it?

Please don't do this (at least if "path" if /usr/bin). Just install the
g++ package.

(And g++-3.3 is most probably not the compiler that was used to compile
the CGAL libraries on Ubuntu. Hence, you will get into trouble in the
linking stage.)
