[GRASSLIST:6159] Re: DEM imports to Grass - missing libproj.so

[Vincent Schut]

libproj.so comes from Proj.4, a free geographic reprojection library. You can 
obtain it from http://www.remotesensing.org/proj/ .
Why GDAL needs it just to give you info on your datafile I don't know. I would 
think GDAL just and only loads this lib when reprojection is needed. It is 
not directly linked to it. So you will not have to recompile GDAL after 
installing Proj. Just running ldconfig should do.
However, if you can compile the install of proj is easy, and it will probably 
solve the error...

Vincent Schut.
