The big issue I’m concerned about is update/upgrade-ability. They did have a lot of close consultation with the Rails Core team, so it should be good, but we’ll see… ---

In addition to rails gems, it comes bundled with just about every gem you might need right out of the box. I guess I’ll be waiting to pick up a box to see the final list. What I really want to know is what sort of D-Trace support is there. Is it just C and OS probes or have they put something together like Joyent [0](https://dtrace.joyent.com/projects/ruby-dtrace/wiki). Brian. ---

Let’s try this again (as posting on [groups.google.com](http://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? ---

Feel free to report any OSX-related problems at [http://bugreporter.apple.com](http://bugreporter.apple.com) You can attach files (patches) there. Thanks, Laurent ---

In that case - please find attached the patch for Ruby 1.8.6+p111 (the latest security fixes) which works on Apple OSX Leopard and provides full DTrace support. The ‘bugs’ aren’t bugs so much as differing implementation. Although not being able to compile objects is a little bit of a pain. Cheers, Lee. ---

I hope he’s the right person. I am no longer with Joyent, so if you mailed scott@joyent it wouldn’t get to me (you can use this address or, preferably, removed\_email\_address@domain.invalid) and I can help you out. -Scott
