From Lifeng Sun: Since ruby-1.9.1 the header files are installed in a sub-directory, i.e. "include/ruby-1.9.1/", and CONFIG["includedir"] is no longer the right place to find the headers. I also fixed the the ruby library dectection on system with multiple versions of ruby, but it's only a dirty hack for linux and several other unix variants.
