Postgis-connection

I want to use a postgis database. the geometry lies in column 'the_geom' of
table 'test'.  Now I got this error message:

msDrawMap(): Image handling error. Failed to draw layer named 'TEST'.
prepare_database(): Query error. Error executing POSTGIS DECLARE (the actual
query) statement: 'DECLARE mycursor BINARY CURSOR FOR SELECT
asbinary(force_collection(force_2d(the_geom)),'NDR'),gid::text from test
WHERE the_geom && setSRID('BOX3D(4494500 5258000,4680500 5444000)'::BOX3D,
find_srid('','test','the_geom') )'

Postgresql reports the error as 'ERROR: could not load library
"C:/ms4w/apps/pgsql75win/lib/libpostgis.dll": error '


what is my mistake ??? the mapfile seems to be OK.
