Thanks for the info. I will include it in my setting. However, it i was  
not what I was looking for. I do not suppose you know how to tell  
NetBSD the number of compile jobs to run at once? It is the -jX  
switching in make I believe. I have 4 cpus and want make sure that a  
build uses as many as it can.

Take a look at Section 5.e at the bottom of the section, Code Listing  
18. (From Gentoo Linux) 

How do I do this in NetBSD?
