I decided to go with an awk-less solution to try to reduce pkgsrc's 
dependency on awk.  I did mention in my talk at pkgsrcCon that since we 
use awk quite pervasively in pkgsrc, we should probably add it to the 
bootstrap kit.  Thankfully, we now have a BSD-licensed awk in src that 
we can distribute in the bootstrap if we wish.
