Building KDE 3.5.11

Typical free/libre software practice when providing packages is to also provide the sources and build scripts at the time the packages were made. Is there a snapshot available of the sources from the day when you issued the Trinity 3.5.11 packages? In addition to our current efforts I would like to try building from the 3.5.11 sources. I want to start using Trinity KDE at some point after the stock 3.5.10. The build process might again fail --- I don't know about that because of some of the Debianization that we are troubleshooting now --- but I'd like to try. Darrell
