Problems with pacman when upgrading to xorg7

Question

I decided to try and update from xorg-11R6.8 to 7 tonight, after hesitating for a while. I saw all the bug reports and problem threads, and I still can't understand why something that results in so many bugs has been released. It doesn't seem to comply with the KISS principle, either, but who am I to judge?
Anyway, my problem is this:
When I try to install the xorg components, I get the following message in my terminal. After checking the packe intergrities, it'll go to install the first package and then show this:
load_pkg: missing package name in /var/cache/pacman/pkg/libxkbfile-1.0.1-1.pkg.tar.gz.
After removing xorg-11R6.8, it will do this for any package I try to install, whether part of the new modular xorg or not.
If I do a "pacman -U /var/cache/pacman/pkg/xorg-11R6.8.2-6.pkg.tar.gz", it works fine again.
I've read through the Xorg7 wiki entry and there's no reference to this problem.
Any way to solve it?
Thanks in advance.

Answer 1

That didn't really help, either.
Apart from a fresh install, is there anything I can do to just sort out all these stupid problems in one go?
When I try and upgrade to xorg7, I get all these messages about missing object files and libraries, complaints from /sbin/ldconfig about the nvidia module being empty, all this other crap too; it seems like a different thing broken every time. When I downgrade to xorg-6.8, fluxbox comes up and works, but when I go to upgrade anything else with pacman, I just get the load_pkg errors or whatever else.
I've tried editing my /etc/X11/xorg.conf file to the new xorg7 paths when upgrading to xorg7, but it makes no difference.
I don't understand how something that's supposed to simplify Arch could break things for so many people, =
