Research direction
Start by reproducing the tile-rendering failure after changing the OpenStreetMap style to osm-bright, then inspect the projection transformation path and the build configuration for -DMAPNIK_USE_PROJ4. Done means the reported projections initialize and the default tile renders without the proj4-support error.
