There is another option: Radim Blazek wrote a new GDAL/GRASS driver
(see QGIS project for details). Frank considers to replace the old driver.
The new driver uses the GRASS libs directly, so the external 'libgrass'
is no longer needed then.

IMHO not recommended.

As far as I understood the Debian grass maintainers, there will be
no GRASS 5.7 included into Debian in the near (far?) future.

Let me vote for the GDAL/GRASS driver replacement, which might be 
faster than waiting that GRASS 5.7 reaches Debian one day. Debian
is still at GRASS 5.0(!).3 (there is also 5.3.0) but this doesn't
belong here.
