First getting started I recommend sticking the the merc/900913 default
projection that osm2pgsql uses to import the data and which the
stylesheets assume.
Often blank maps indicate a projection problem, and in the case of
PostGIS, prior to Mapnik 0.7.0 could be resulting from failing SQL
queries sent by Mapnik to PostGIS that went unnoticed (without obvious
error).
Are you running Mapnik 0.7.0? If not I'd recommend upgrading which may
help you slightly to understand how to get things set up correctly.

Hi, this is David. I finally managed 'generate_tiles.py' to work but
it generates only empty tiles. I've removed coastline shapefile
reference from my local xml file as Dane suggested. My PostgreSQL
database parameters(host, port, etc.) are OK. I've tried both
latlong and merc projections with no success. Can someone help me to
figure out what's wrong?
