[Tilecache] Use of tileCache with Mapnik

[kryptonite]

Hey Arnaud, 
                 I think you got over with your problem and have a running
map. I am having trouble getting this simple demo thing to run with
mapnik+openlayers+tilecache..

below are my files that i have and all that I got was pink tiles. The tiles
are not being created too.


openlayers : index.html
var map, layer;

        var options = 	{
								 numZoomLevels:10,
								 maxResolution: 360/512,
								 projection: "EPSG:4326"

							  };

			    function init(){
				            map = new OpenLayers.Map( 'map', options);
				            layer = new OpenLayers.Layer.WMS( "VMap0",
				                    					"http://localhost/cgi-bin/tilecache.cgi?",
				                    					{
				                    						layers:'basice',
				                    						format: 'image/png'
				                    						srs: 'EPSG:4326'
														}
									 );
				            map.addLayer(layer);
				            map.addControl( new OpenLayers.Control.PanZoomBar());
							map.addControl( new OpenLayers.Control.MousePosition());
						    map.addControl( new OpenLayers.Control.LayerSwitcher());
						    if (!map.getCenter()) map.zoomToMaxExtent();

        }
