The Mac OS X "dtrace -h" emits all the information required for successfully linking a USDT probe by the rest of the toolchain. On Mac OS X "dtrace -G" is superfluous. For historical reasons "-G" was disabled early on in the bring up. We'll take a bug to re-introduce "- G" as a no-op with a warning message. See the section "BUILDING CODE CONTAINING USDT PROBES" in the Leopard dtrace(1) man page. Static probes work very nicely on Mac OS X (thank you!) A number of our frameworks ship with "Is Enabled" static probes in Leopard.
