You would need to load some Pier addons:
    http://www.piercms.com/doc/add-ons

You would specifically need " Pier-Kernel-Distributions".

V2 addons are available at:
MCHttpRepository
    location: 'http://source.lukas-renggli.ch/pier2addons'
    user: ''
    password: ''

V3 addons are available at:
MCHttpRepository
    location: 'http://source.lukas-renggli.ch/pier3addons'
    user: ''
    password: ''

PierCMS V3 source is now available at:
MCHttpRepository
    location: 'http://smalltalkhub.com/mc/Pier/Pier3/main'
    user: ''
    password: ''

But, it looks like that V3 addons are not yet available http://smalltalkhub.com/#!/~Pier/Pier3/source.
