OK. This is the old stable branch (I think). If you can get 2.0 to
compile I would suggest trying that.
Dylan, which one is 2.0 for linux? Can't trace it.

Great news! thanks Glynn
There is currently no way to
calculate the mode, although I'm unsure whether that is a meaningful
concept for floating-point data.
I agree, mode is about frequency so

Giovanni,
sorry for the sort-of off-topic, but how do you build starspan with
GRASS support? Do you work under Ubuntu? I am trying the following:
I haven't used it with GRASS datas but with a tiff and a shp.
My hypoteses about GDAL/OGR inefficiencies are not related to this case...
Thanks Markus. I'm out of office, but I will try your solution as soon
as possible.
