New xorg fails with "module ABI major version (6) doesn't match the server's version (12)"

[Mike Clarke]

After upgrading from 9.1-RELEASE to 10.0-RELEASE I deleted all 
packages, created /usr/local/etc/pkg/repos/FreeBSD_new_xorg.conf and 
ran "pkg install xorg".

Attempts to run startx failed with an ABI mismatch message so I then 
tried "Xorg configure" which failed in the same way.

The FreeBSD_new_xorg repository was used for some packages but I 
wonder if more of them should have been from there?
