If you browse ftp://ftp.archlinux.org/unstable/os/i686/ you will see two muttng packages: muttng-20060424-1.pkg.tar.gz and muttng-20060827-1.pkg.tar.gz
However, the packages.txt file in that directory lists: network/muttng-20060616-1.pkg.tar.gz

When I attempt to install muttng, the following pacman error is thrown:
pmorris@arch:~ $ sudo pacman -S muttng
