Package: python-vtk6 Version: 6.3.0 This is not a bug but a wishlist item for this package. It would be nice to have a virtual/meta package that automatically links to the latest version of the package. Having a package named python-vtk which links to python-vtk6 now and python-vtk7 in the future will make transitions easier. Below is the link to a package that already implements this.
