/usr/share/proj/epsg is there. I been looking at past list messages with 
similar problems, and they refer to the mapfile having additional 
information, on the projection, for wms access. I added

PROJECTION
   "init=EPSG:4326"
END

to the top of my mapfile and

METADATA
    "wms_srs" "EPSG:4326"
    "wms_format" "image/png"
END

to the layer I am trying to display. Do I need this information in the 
mapfile? Do I need additional information in the mapfile, to give WMS 
access? I am going to look at mapserver documentation to see if they 
have a description on how to do this.
