afaik this isn't possible from within a ruby, or any script.  setuid programs
are gaurded pretty heavily by the kernel.  i worked on this for some time at
one point and this was the only way it was possible at the time:

   http://codeforpeople.com/lib/ruby/setuidruby/

let me know if you figure out another method.  the bottom line is that setuid
program must be binary.

enjoy.
