Arnaud,

Try setting the full path to your shapefile in the XML.

For example:

>             <Parameter name="file">/home/arnaud/data/tuto/ 
> TM_WORLD_BORDERS_SIMPL-0.2</Parameter>


Also, make sure you are pointing to the shapefile name, not the folder  
it is inclosed in.

Lastly, if those things don't help try setting the projection property  
in your config:

  [world]
type=Mapnik
mapfile=/var/www/html/RetD/mapnik/mapfile.xml
layers=world
projection=+proj=latlong +datum=WGS84
