dstat-0.6.5 was released a while ago see the changelog in the url. The main page: http://dag.wieers.com/home-made/dstat/ shows 0.6.4 as the most recent but it's not, 0.6.5 was released a few days later with fixes. A bump probably will work, haven't tested it yet.
I can't find 0.6.5 for downloading. I suspect upstream just adds the changelog entries for 0.6.5 and adjusts the release date, without actually having 0.6.5 released. 0.6.4 is in the tree.
