Pacman fails. gcc-uclibc: requires kernel-headers- What's this???

Question

After my last update a few weeks ago, I always get this.  I've updated kernel, pacman, and initscripts manually, and messed with pacman.conf for days.
Read countless forums posts, googled for hours, tried many "solutions" and can't figure this out.  (enable/disable different repos, SigLevels, db refreshes, etc.)
gcc-uclibc kernel-headers don't seem to exist, and only a few references (of no help, and old)) show up in all my searching.
My system boots normally, and is running OK- just can't get pacman to work, and can't get past this blocker
Can anyone point me in the right direction?  Has anyone even seen this gcc-uclibc/kernel-headers error recently.

gcc-uclibc is not on my system.  I'm following instructions on the issues 2 section of the above mentioned wiki page, and have gotten the list down to this:

However, pacman -Su still gives the blocking error:
[root@myhost wrc]# pacman -Su

[root@myhost wrc]#
The next step gives me this, supposedly all these need rebuilding?  How can this be, as I'm using the Arch Linux binary packages, and have never rebuilt (re-compiled anything?

Quote on issue 2 from the wiki page:
Issue 2: The final "pacman -Su" still has conflicts in /lib
This means that you have files or folders still in /lib or pacman thinks a package apart from glibc still own /lib. You can see which package own files in /lib by using:
find /lib -exec pacman -Qo -- '{}' \+
If any package apart from glibc is listed as owning a file, that package needs to be updated to install its files in /usr/lib. Any files unowned by a package should be moved to /usr/lib and any directories within /lib need deleted (after they are empty...).
If after this the "pacman -Su" still has conflicts with /lib, this is because a package on your system other than glibc thinks it owns the /lib folder. Such packages can be detected using:
grep -R --include files "^lib/" /var/lib/pacman/local/
These packages need rebuilding so as not to include the /lib directory. Then the final "pacman -Su" will successfully install glibc.
You can confirm the update is complete by looking in your root directory to see that lib is a symlink to usr/lib.
