Error on adding EPSG code

[Mark de Blois]

Hi there,

I Am trying to add an EPSG code for Winkel Triple to my MapServer proj 
file but I keep getting the error:
   
    msProcessProjection(): Projection library error. no options found in 
'init' file

I added the entry:

    # Winkel Triple
<1234567> +proj=wintri +lat_1=45 +x_0=0 +y_0=0 +ellps=WGS84 +datum=WGS84 
+units=m +no_defs  <>

to the file epsg (located at /usr/share/proj on my Ubuntu machine) and 
rebooted.

Ogrinfo tells me the following about the shapefile I am trying to serve:

Extent: (-16707480.310734, -10018754.171395) - (16920780.652974, 
9320947.177797)
Layer SRS WKT:
PROJCS["World_Winkel_Tripel_NGS",
    GEOGCS["GCS_WGS_1984",
        DATUM["WGS_1984",
            SPHEROID["WGS_1984",6378137.0,298.257223563]],
        PRIMEM["Greenwich",0.0],
        UNIT["Degree",0.0174532925199433]],
    PROJECTION["Winkel_Tripel"],
    PARAMETER["False_Easting",0.0],
    PARAMETER["False_Northing",0.0],
    PARAMETER["Central_Meridian",0.0],
    PARAMETER["Standard_Parallel_1",45.0],
    UNIT["Meter",1.0]]

In the mapfile I am referencing this shapefile through:

LAYER
 NAME 'WTCountries'
 DATA 'maplecroft_countries_winkel_45'
 STATUS off
 TYPE Polygon
 
 METADATA
  WMS_SRS  'epsg:1234567'
  WMS_TITLE 'Countries_WT'
  WMS_FEATURE_INFO_MIME_TYPE 'text/html'
 END #METADATA
 
 PROJECTION
   'init=epsg:1234567'
 END

Does anyone have any idea what I am doing wrong? Your help would be 
greatly appreciated!

cheers,
