projection offset

Hi all,

I've got a problem with reprojecting data (shapefiles) with mapserver:
I've got data in shapefiles as wgs84 (epsg:4326) I need to be able to  
reproject them in various coordinatesystems. However if I request the  
data as dutch RD (epsg:28992) and overlay it with a shapefile with  
the same data in epsg:28992 I get a vertical offset. (see attached  
image; the red and black line should overlap.)
If I reproject the data as UTM 30 I get a horizontal offset. Is there  
a magic trick to get mapserver reprojecting data on the fly? I've  
attached my mapfile if that helps.

regards,
Steven
