Let’s try this again (as posting on groups.google.com appeared to
break - so sorry if this has appeared more than once).
Apple have included no ustack helper in Ruby which comes with OSX - so
you have to compile your own.
I have produced a patch for Ruby on OSX and e-mailed the details to
scott at joyent. I hope he’s the right person.
It seems that Apple have broken the ability to use the -G parameter on
dtrace. Meaning you can’t compile d scripts into linkable objects.
This breaks the patch by the joyent guys. Hence me working out a
solution for it.
I now have it all fully working. If Scott’s not the right person - who
should I send it to?
