... /usr/local/lib/libgdal.so.1 ? Did you have a custom installed version
of GDAL in /usr/local? That may be the conflict.

I think it's actually GDAL which wants GEOS 3.1.1, the problem comes
along to GRASS through there when GRASS loads in GDAL.

I'd heard it prefers fresh installs to in-place upgrades, but I've never
tried it myself.

I'd be confident that your data is ok, GRASS can be loaded onto any other
computer of opportunity to access it in an emergency.

Look for files related to an old GDAL version in the /usr/local/ dirs.
