[Tilecache] An error occurred: Current x value ... is too far from tile corner x ...

[Dane Springmeyer]

Chris,

Ya, why don't you try getting things working without the custom  
bounding box?

Something as simple as this should work:

// OpenLayers Map Options
var options = {
     maxResolution: 156543.0339,
     units: 'm',
     projection: new OpenLayers.Projection("EPSG:900913"),
     maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34,  
20037508.34, 20037508.34)
     };

# TileCache.cfg

[your_layer]
type=Mapnik
mapfile=/full/path/to/mapnik.xml
spherical_mercator=true
