Arch Linux

I am following the "Building_in_a_Clean_Chroot" wiki article page but am getting errors I can't rationalize. I can confirm this error on my workstation (x86_64 with [testing] enabled) and on an older fileserver (i686). Flagged as critical since key functionality is seemingly missing confirmed on two machines.

$ mkdir /media/data/archbuild
$ CHROOT=/media/data/archbuild/root

$ sudo mkarchroot $CHROOT base base-devel sudo
<< install completes successfully >>

$ cp /var/abs/core/glibc ./ && cd glibc

$ sudo makechrootpkg -c -r $CHROOT
