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

[Dane Springmeyer]

Try putting:

projection= +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0  
+x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs +over

or

projection= +init=epsg:900913

in your tilecache.cfg
