reinstall all of Xorg

[n dhert]

After an upgrade FreeBSD72 -> 80, Xorg doesn't work
looking in /var/log/Xorg.0.log tells
Build Operating System: FreeBSD 7.2-RELEASE-p7
Current O S  FreeSBD-8.0-RELEASE-p2

I have done a portupgrade -af after upgrading, but somehow if seems not to
have done this for Xorg ??
How can I reinstall anything of Xorg ?

Will this do the job?
# cd /usr/ports/x11/xorg
# make clean
# make deinstall
# make reinstall clean
or
# portupgrade -f xorg

i'm confused and would like to get it right ...
