Subject: extending ruby with C++

I'm using this old (2001) mini tutorial:

http://www.angelfire.com/electronic2/issac/rb_cpp_ext_tut.txt

When I run make, I get this error:

$ make
cc  -bundle  -L"/usr/lib" -o Test.bundle Test.o  -lruby  -lpthread -ldl
-lobjc
/usr/bin/ld: Undefined symbols:

make: *** [Test.bundle] Error 1

$ ls
Makefile        Test.cpp        Test.o          extconf.rb

I tried that on mac osx.  Any idea what's wrong?
