[ gpsdrive ] Mapnik module

[Alex Cruz]

The story so far:
I ran mapnik-osm-updater.sh --grant_db_users=* and that fixed the permissions 
for my user. Next, I ran ./mapnik-osm-updater.sh --count_db --debug and this 
is all that came back:

osm2pgsql SVN version 0.50-20071015 $Rev: 4895 $

Usage:
        osm2pgsql [options] planet.osm
        osm2pgsql [options[ planet.osm.{gz,bz2}
        osm2pgsql [options] file1.osm file2.osm file3.osm

This will import the data from the OSM file(s) into a PostgreSQL database
suitable for use by the Mapnik renderer

Options:
   -a|--append          Add the OSM file into the database without removing
                        existing data.
   -c|--create          Remove existing data from the database. This is the
                        default if --append is not specified.
   -d|--database        The name of the PostgreSQL database to connect
                        to (default: gis).
   -l|--latlong         Store data in degrees of latitude & longitude.
   -u|--utf8-sanitize   Repair bad UTF8 input data (present in planet
                        dumps prior to August 2007). Adds about 10% overhead.
   -s|--slim            Store temporary data in the database. This greatly
                        reduces the RAM usage but is much slower.
   -h|--help            Help information.
   -v|--verbose         Verbose output.


--------- Check Number of lines in Database

I then ran "python scons/scons.py PREFIX=/usr PROJ_INCLUDES=/usr/include 
PROJ_LIBS=/usr/lib" in order to fix the pathing for mapnik. When I start 
gpsdrive from the command line, I receive this output:

I now have roads defined however, there are no names listed. Next, I ran 
python to check the mapnik module. The output:

>>> from mapnik import *

Any thoughts as to why the street names are not displaying?

P.S. I install the world boundaries, too.
