[GRASS-user] reprojection from Projection Mollweide

Hy everyone.
I have a problem with a reprojection.
I have a global raster (a grid esri) that I imported (by choosing the file
w001001.adf) in one location. I created the location with a reference system
that has these parameters (in a file prj.adf):
Projection Mollweide
Zunits NO
Xshift 0.0
Yshift 0.0
Parameters 6370997.0 6370997.0
   0 0 0.0 / * Longitude of projection center

So far so ok.

Then I tried to reproject the raster in a location with  ETRS_1989_LAEA but
I get (at least on Italy) a strong localization error.

I tried also  with WGS84 (EPSG 4326) but nothing....and even from the
command line making various adjustments to the parameters .. for example:
gdalwarp-s_srs "proj = moll ellps sphere lon_0 = 0 = x_0 y_0 = 0 = 0
a=6370997 b=6370997 no_defs units=m "-t_srs "EPSG : 4326 "map.tif

Does anyone have experience on?
