I am cross-posting back to dtrace-discuss, since the Apple folks listen...
I'm not sure what your hello world program is doing. I tried the same thing
with compiled C code.
The problem I ran into with hello world, and with the date example, is

When you say "straight from the dtrace book", I assume you mean
the soon-to-be-published book?
If that is the case, please allow me to clarify. Not every invocation of dtrace,
both one-liners and scripts, that are in the book (and there are hundreds) is
tested and guaranteed to work under all thr
