Right, so I started this and it's as fun as it is. However, before I dig deeper into my current rabbit hole, mapnik needs libicuuc.so.63, but SFOS 3.4 target has version 66 (confusingly, libicu package) - will this be a matter of cloning pkg-mapnik and creating another rpm for mapnik (adjusting whatever version needed, of course)? mapnik says it prefers libicuuc >= 4.2, I believe 66 is significantly bigger than 4.2, unless I have something categorically wrong - mathematics or package names Thanks!
