Many new users of ArchBang are having serious problems updating after installing the May release. We are well aware of the problem, but there is no easy fix. If you have tried to update right after install then there is a good chance the problem can be resolved by removing broadcom-wl drivers.
As a rough guide:
sudo pacman -Syy
sudo pacman -R broadcom-wl
sudo pacman -Syu --ignore glibc,curl
sudo pacman -Su
If you need broadcom drivers then:
# packer -S broadcom-wl

We are working hard to get a new set of testing isos released to resolve the issue. With previous recent changes to the Arch Linux system (/lib to /usr/lib, Grub to Grub2, etc.), we are in the process of creating a new release at the moment and once we have a working iso set, the AB team will put it out for testing.
