* Added README.source. Thanks Manuel Montecelo. * Removed FindGDAL.cmake file supplied by upstream since it does not detect current libgdal1-1.6.0. The script provided by CMake works fine. * Removed openthreads-doc since OpenThreads documentation is shared with OpenSceneGraph's, hence this package was empty. * Now ccache handling is being done automatically by CMake. * Drop conflict dependencies with previous versions to let them coexist with current ones (Closes: #580079 #580081).
