This will be a "dependency hell" problem between GDAL and GRASS binaries, 
probably a stale GRASS GDAL plugin somewhere. It has been seen on Debian 
based distributions before, for example:

http://lists.osgeo.org/pipermail/grass-stats/2009-July/001105.html

Most likely you have multiple GDAL and/or GDAL binaries that do not like 
each other, and because of the possible reverse dependence in the GDAL 
GRASS plugin, they get in each others' way. The grass-stats list may be a 
good place to ask too.
