Updating KDE

[Jerry]

I was just perusing <https://wiki.freebsd.org/Graphics> as shown in the
UPDATING file regarding KDE4. I saw the following notation:

Enable in /etc/make.conf: 
WITH_NEW_XORG=yes
WITH_GALLIUM=yes 

I am running "FreeBSD 10.0-RELEASE #0 r260789" with a nVidia card using the
latest nVidia driver available in the ports system. Do I have to enter that
information shown above in my "/etc/make.conf" file prior to updating KDE?
