Please update to spearfish60 to avoid region problems.

what does

gdalinfo /home/hamish/grassdata/spearfish57/PERMANENT/cellhd/elevation.10m
say?

What does

 ldd /usr/lib/gdal_GRASS.so

say?

AFAIK the plugin directory must be ../gdalplugins:

grep gdalplugins ./gcore/gdaldrivermanager.cpp
 * Search in lib/gdalplugins instead of directly in lib directory.
 * the /usr/local/lib/gdalplugins directory, and (if known) the lib/gdalplugins
                                        GDAL_PREFIX "/lib/gdalplugins" );
                                        "/usr/local/lib/gdalplugins" );
                                                   "lib/gdalplugins", NULL ) );

So it won't work if installed as /usr/lib/gdal_GRASS.so
(should be /usr/lib/gdalplugins/gdal_GRASS.so ?)

Hope this helps
