Compiling Mapnik on OSX:

reprojection always seems to be from whatever is specified as srid in grainstore to EPSG:3857. So assumption seems to be that all layers in database will be in same projection.

    grainstore: {
                 datasource: {user:'postgres', host: '127.0.0.1', port: 5432, srid: 4326}
    }, //see grainstore npm for other options
