I don't know where this issue should go since it involves different projects, but since my Aegir instance has installed several other distros, I thought I'd start here.

There's a similar issue reported here: http://drupal.org/node/1807516

And I've attached Aegir's log.

(Heard about Nodemaker on Module's Unravelled podcast and thought I'd check it out.)
