[GRASS-stats] multiple grass installations and spgrass6()

[Roger Bivand]

The message is coming from GRASS, almost certainly from v.out.ogr, and 
almost certainly because you have multiple versions of GDAL on your system 
(or a GDAL component or plugin). I am not able to help with GRASS 7 
problems, it is an unstable development version. Can you export the object 
to a vector file in GRASS itself, not inside R? Does the same error occur? 
Does the error rather (or also, if GDAL is broken) occur on reading a 
shapefile into R with readOGR()? You'll have to separate the problems 
yourself until you find out which software component is wrongly linked to 
GDAL - best to remove all binary installs of GDAL which on Debian/Ubuntu 
are notorious for causing trouble, and install GDAL from source, then 
re-install GRASS from source, and rgdal from source.

at the ends of the threads. In both cases the GDAL/OGR GRASS plugins were 
the culprits, often caused by binary installs of GDAL.
