Tom,

IIRC, my laptop version of xastir had me compile separately GDAL. BigBox 
got GDAL from the repo.

All I can say is "AIIIEEEEEEE" as he runs into the darkness, holding his

Changing the variable names, I believe that what was done,  that was done in the CVS , avoided the linker bringing in libgrass_rtree because it could not find the symbols. What I find interesting is that nm can't find any labels in libgrass_rtree. Maybe I did not pick the right option. But that can be for another time. Have to tackle the outside honeydo list.....
