[Proj] Mapserver Projection Issue

[Richard Greenwood]

Are you sure that it's finding and using the correct epsg file? You could
specify the full path to an epsg file in either the mapfile or the apache
conf, or paste the proj parameters into the PROJ block in the mapfile and
do away wit the epsg file completely.
