Relace the definition above with:

Proj4js.defs["EPSG:102003"] = "+proj=aea +lat_1=29.5 +lat_2=45.5
+lat_0=37.5 +lon_0=-96 +x_0=0 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m
+no_defs";

Replace the above to lines with:

  var source = new OpenLayers.Projection("EPSG:4326");   
  var dest = new OpenLayers.Projection("EPSG:102003");

Regards,
Andreas.
