New installation of xorg 7.2 from ports

[Bruce Cran]

Are there any manual steps necessary to install xorg 7.2 on a machine 
without an existing installation?
I did a "make install" in /usr/ports/x11/xorg and got the following error:

...
===> Registering installation for libdrm-2.3.0
===> Returning to build of dri-6.5.3,2
===> dri-6.5.3,2 depends on shared library: X11.6 - not found
===> Verifying install for X11.6 in /usr/ports/x11/xorg/xorg-libraries
Read /usr/ports/UPDATING for the procedure to upgrade to xorg 7.2.
*** Error code 1

It looks like that message gets displayed if XORG_UPGRADE and 
PACKAGE_BUILDING are undefined.  Since this isn't an upgrade do I still 
need to set XORG_UPGRADE anyway?
