The awstats package in Debian is pretty outdated. Etch has version 6.5. Sid has 6.7. Version 6.9 was released on December 28, 2008. I’m a statistics junky and the new version has better robot detection so I built an updated package on my lenny/sid machine: awstats_69-1_all.deb. This package also works perfectly on my etch server without changes.
I did apply all the Debian patches that were still relevant so it should be the equivalent of the official Debian package.
