I would capture first the image of your area by using native EPSG:900913
projection with gdal_translate and WMS driver as described at the bottom of the
document http://gdal.org/frmt_wms.html.  As a result you will have on a disk a
geotiff file which is simple to re-project further into EPSG:2180 with gdalwarp.
