No, my OGR library was not compiled with GRASS support! :-)
sorry...

What exactly should I do?

I've downloaded the last version of gdal-svn and configured it, with:
{{{
./configure --prefix=/home/pietro/.local/ \
     --with-grass=/home/pietro/docdat/src/gis/grass/grass_trunk/dist.x86_64-unknown-linux-gnu
\
     --with-netcdf  \
     --with-libtiff  \
     --with-sqlite3  \
     --with-geotiff  \
     --with-python=/usr/bin/python2  \
     --without-libtool --with-curl  \
     --with-hdf5  \
     --with-geos  \
     --with-png
}}}

But compiling I got:
{{{

Any hints?
