Pirmin, While preparing the fix for gdal, I realized that osgearth had better to build-depend on libgdal-dev instead of libgdal1-dev, this will save our time when gdal has a major version bump. I've committed this change to pkg-grass git repository. And you may have already seen I've started a new topic about gdal if you have subscribed to debian-gis@l.d.o, there is more problem to solve than expected, so please be patient, :-) -- Regards, Aron Xu
