If I force deactivate vtk before upgrading it, it works fine:

So a file or files which used to be provided by the vtk port are now provided by vtk's dependency xdmf. So xdmf needs to employ the deactivate hack to deactivate vtk, if a vtk of that vintage is active.

Are we sure that /opt/local/include/ProjectVersion.hpp is a file that should be installed at all by any port? Its name sounds very generic, such that I would not expect such a file to be installed in a public include directory.
