    @$(ECHO) processing probes in object files
    $(Q) $(RM) $@
    $(Q) $(DTRACE) -G -C $(INCFLAGS) -s $(srcdir)/probes.d -o $@ $(DTRACE_REBUILD_OBJS)

after I add -64 to dtrace command:

$(Q) $(DTRACE) -G -C $(INCFLAGS) -s $(srcdir)/probes.d -64 -o $@ $(DTRACE_REBUILD_OBJS)

the error will gone, and it finishs compiling, but I still don't get ruby probes

dtrace -l | grep ruby

the command returns nothing.
