vtk6 does not build against proj ≥ 4.7
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
vtk master as of circa May 2013 does not build against proj ≥ 4.7, making it impossible to build against system packages of the same, due to upstream API changes.
Please update the version of proj in VTK and modify the code to work against the current API.
