Click on Install from repository, then click the "Services" link. Check off "Developer Support" and click the "Download" button at the bottom of the page.
Yep, it was right there under services. However I didn't have the option to download, only to "install or upgrade checked applications". However, once I tried to install I got an error. Please see my other post for more information: https://openacs.org/forums/message-view?message%5fid=1542796
