"g++ rs_example.C -lCGAL" works for me. There might be a problem with
your GMP/MPFR installation.

It might be helpful if you'd provide more information, e.g. operating
system/linux distribution & version, compiler version, CGAL version,
GMP/MPFR version, whether you compiled GMP/MPFR/CGAL yourself or whether
you're using precompiled packages.

Does it work if you use the makefile provided by CGAL?
