Using 2 CPUs with BIND

I increased the logging to the debug level, but still no mention of it 
using 2 CPUs. In fact, I don't get the line "found X CPUs, using Y worker 
threads" at all, even mentioning one CPU. Even with the switch '-n 2", it 
doesn't give any error that it didn't find two CPUs. Is that Linux only? 
Is there anything I need to add during compiling for this to work?
