-fomit-frame-pointer IS EVIL. Do not use it. portupgrade won't build
with it, cause ruby hates -fomit-frame-pointer. I would just do a
fresh binary install. 6.0 is quite an amazing release... The speed
is remarkable. My machine goes way faster than it did before.
I am using the following CFLAGS successfully with xorg and XFCE4:
CFLAGS=3D-O2 -pipe -ffast-math
CPUTYPE=3Dp4
I can't speak to building FreeBSD from source. I build all my ports
from source, but didn't bother building the world from source...
