You can either change the URL in the javascript to include
the /osm_tiles2/ part of the URL, or you can use mod_rewrite to fix it
on the server. The live OSM server uses the rewrite rules because
historically people have been using a variety of different URLs to
access the tiles:

        RewriteEngine on

        RewriteRule ^/([0-9]+)/([0-9]+)/([0-9]+).png/status  /osm_tiles2/$1/$2/$3.png/status [PT,T=text/plain]
        RewriteRule ^/([0-9]+)/([0-9]+)/([0-9]+).png/dirty   /osm_tiles2/$1/$2/$3.png/dirty  [PT,T=text/plain]

        RewriteRule ^//?(-?[0-9]+)/(-?[0-9]+)/(-?[0-9]+).png               /osm_tiles2/$1/$2/$3.png   [PT,T=image/png]
        RewriteRule ^//?mapnik//?(-?[0-9]+)/(-?[0-9]+)/(-?[0-9]+).png        /osm_tiles2/$1/$2/$3.png   [PT,T=image/png]
        RewriteRule ^//?mapnik_tiles//?(-?[0-9]+)/(-?[0-9]+)/(-?[0-9]+).png  /osm_tiles2/$1/$2/$3.png   [PT,T=image/png]

You want to enable it, having "#define DIRECTORY_HASH" is sufficient,
you don't need to change this line.
