Some folks have complained that they couldn't build the dist because we removed the ant distro from the "ant" directory and they couldn't find that particular version. I should point out that any version 1.6.1+ should work. The build just is picky on the file name (we could change that but I'd rather default to known good). Heiko complained when I had ant in CVS so I removed it. Thus I have attached it to the Wiki:

That should make everyone happier.
