Hi Vishal,

Are you positive that you are invoking the latest gdal tools and libraries? I 
would remove any that you have installed via package manager (aptitude, 
etc.), and then run"

gdal-config --version

after removing the packaged version, it might also be a good idea to run 
ldconfig (as root).


Cheers,

Dylan
