Ok, everything in that section seems clear except this in 3.3:
It is possible to completely replace CFLAGS and/or define custom CPUTYPE 
as well. We recommend setting CPUTYPE because many ports decide their 
optimizations flags based on this variable.

How do I figure out what to set for CPUTYPE? Also, what else should I 
include in CFLAGS besides -mssse3?  I have a core 2 duo processor, which 
says this at boot time:
CPU: Intel(R) Core(TM)2 CPU         T7600  @ 2.33GHz (2330.23-MHz 
686-class CPU)
   Origin = "GenuineIntel"  Id = 0x6f6  Family = 6  Model = f  Stepping = 6

Thanks!
