    This is not entirely correct. Sure, your system will run without anything
    special in make.conf; But if you want decent performance, you probably
    want to set CPUTYPE to "nocona" in order to get a build that is tailored
    to your cpu (SSE3, etc). More information on what that CPUTYPE enables is
    available in /usr/share/mk/bsd.cpu.mk.

    Cheers,
    Andy
