Perhaps we should start to think about library re-organization now,
to address (for 5.1)
 - cleanup of mixed libraries
 - extract the IO routines to support libgrassio (Frank Warmerdam)
 - support shared libraries
 - add the new makefile system (package is in grass51/ in CVS)

and keeping 5.0 as is for this issue.

Since David can't support GRASS these days due to other business,
the GSTAT or R are candidates for kriging. Both support GRASS
