[GRASS-stats] Incompatible library version for module SOLVED but new problem with plugin=TRUE has emerged

[Roger Bivand]

The changes to handle finding files in other mapsets and to remove 
confusing messages have been included in spgrass6_0.5-17, now released on 
CRAN. It checks cleanly against 6.4.0svn, Revision: 35395, so RC2 is good 
too (this is the svn up number, but the number in Help -> "About GRASS 
GIS"  in the wxpython GUI is lower - any way to harmonise?).
