It's not the BUILD-depends of vtk that are relevant but, rather, the regular dependencies of gdcm's build-deps. For example, installing libvtk5-dev will pull in anything that libvtk5-dev depends on. While vtk is linked with tiff (package libvtk5 depends on libtiff4), the package libvtk5-dev does NOT depend on libtiff4-dev. This may be an oversight, but more likely it reflects the fact that you can use VTK without needing TIFF so there is no need to force all libvtk5-dev users to install the TIFF development package. But gdcm apparently uses the TIFF-using part of VTK, so gdcm must build-depend on libtiff4-dev. Hope that clarifies things. -Steve
