Espen, Great, thanks for reporting back!
Note in trunk we now have: mapnik.has_cairo() function which indicates whether cairo/cairomm support was compiling into the libmapnik.dylib and mapnik.has_pycairo() function which indicates support for pycairo (compiled into Mapnik python bindings + the availability of the 'cairo' module) Dane On Nov 16, 2009, at 11:01 AM, Espen Isaksen wrote: > Ok, that did the trick.
