Mapnik 2.1 is now available: This release adds many new features, but maintains back-compatibility with Mapnik 2.0.0. http://mapnik.org/news/2012/08/24/release-2.1.0/ Mapnik development now takes place on github [1] so anyone that runs into issues upgrading please post there. Cheers, Dane [1] https://github.com/mapnik/mapnik/issues
