Sorry, there was still one old file "rcgal_apollonius.cpp" in that
directory, but its makes no difference. Just removed it and made a new
clean build, build process is fine:

stefan@AMD64X2 ~/tust $ ls -l

-rw-r--r-- 1 stefan stefan 196 Oct  8 19:43 extconf.rb
-rw-r--r-- 1 stefan stefan 618 Oct  8 19:42 hello_world.cpp
stefan@AMD64X2 ~/tust $ cat extconf.rb 
require 'mkmf'

if have_library("CGAL") and have_library("CGAL_Core") and
have_library("gmp")
  $CFLAGS += " -frounding-math"
  create_makefile("hello_world")
else
  puts 'missing CGAL library'
end
stefan@AMD64X2 ~/tust $ ruby extconf.rb
