[GRASS-user] Two questions

1) I have installed Grass-6.3 (compiled from source to work on Ubuntu / 
Freespire). The new installation can't see the mysql driver (although 
6.2 still sees it). How do I tell Grass-6.3 where the driver is?

2) More complex, a question about polygons. I have maps with large 
numbers of polygons with shared boundaries. Is there any way to count 
the number of boundaries one polygon shares with its neighbors?
