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 ?
