Comment (by moses at moseshohman.com):

 I have done this on my own (see http://rubyforge.org/projects/rubyport-
 dtrace). I would be happy to contribute that work back into MacPorts. It
 required some massaging of the Joyent DTrace patch to get it to compile
 with Apple's version of DTrace (which doesn't need to create a dtrace.o
 object file, just a dtrace.h header).
