  You need to use an OUTPUTFORMAT with the format options to have the 
color reduction, which is not available by default. So your OUTPUTFORMAT 
would be somethig like:

OUTPUTFORMAT
      NAME "agg/png24"
      MIMETYPE "image/png; mode=24bit"
      DRIVER "AGG/PNG24"
      EXTENSION "png"
      FORMATOPTION "PALETTE_FORCE=TRUE"
      FORMATOPTION "PALETTE=/u/data/maps/palette-google-agg.txt"
    END
