It is on a users machine and not here. One theory is that Xcode is set to
$(NATIVE_ARCH) (note this is not a Universal Binary app yet). And Xcode is
running on a G4.
I assumed based on the Xcode description that $(NATIVE_ARCH) would become
ppc, but perhaps it is becoming ppc7400 and thus G4 code which runs on a G5
but not G3.
