map projection problem

[blaise]

Hi,
Not very familiar wit Projection's use, but your EXTENT datas seems strange. 
Have you tryed to open your "boundairies" shape file in ArcView to look at 
the extent ?
First, as seemed to be set in your mapfile, your "boundairies" shape file 
should stand in your /var/www/tmp directory. (bit strange, by the way, as it 
seems to be also your temporary images directory).
Second, if you can't figure out your shapefile extent, send your shape file 
(esri shape, I suppose), and I'll try to find the right extent.
