Can you compile the Host.cpp file referenced in :
http://lists.freebsd.org/pipermail/freebsd-current/2011-May/024499.html

And see which arch the resulting binary detects ?

%clang++ Host.cpp -o Host
%./Host
cpu = corei7

Also, do you have the same problem for a clean buildworld with
"-march=athlon-xp" instead of "-march=native" in your make.conf ?

Cheers
