[ka-Map-users] First ka-map attempt..

I have not been able to figure out why I'm unable to display map tiles.   I 
am still getting the "dead image" icon flashing sequentially through the 
various tile locations.     It does appear to be generating the meta 
tiles... but so far as I can tell it is not creating the small tiles.

When I look in the cache directory, I see this structure:

in each of those last directories is a meta directory which contains the 
meta tile.png.
There is no directory created for small tiles... and if I'm understanding 
correctly it's the small tiles that it's trying to display when it is 
flashing the dead image icons.

Here is my configuration:
the gmap-ms40 map file is stored in /var/www/map/gmap-ms40/htdocs
kmap is installed in /var/www/map/kamap/htdocs
in the kamap config.php file:
$szPHPMapScriptModule = 'php_mapscript.'.PHP_SHLIB_SUFFIX;
$szPHPGDModule = 'php_gd.'.PHP_SHLIB_SUFFIX;

$tileWidth = 200;
$tileHeight =200;
$metaWidth = 5;
$metaHeight = 5;
$metaBuffer = 10;
$aszMapFiles = array(
  "gmap"   => array( "GMap", "/var/www/map/gmap-ms40/htdocs/gmap75.map",
                     array( 15000000, 7500000, 3000000, 1000000 ),
$szMap = 'gmap';
$szBaseCacheDir =  "/tmp/kacache/";

Anybody have any suggestions on why it seems the small tiles are not being 
created?   The meta tiles are created so I assume that it isn't a 
php/mapscript problem and i'm not getting any php/mapscript related errors 
in my apache error logs.
