vtk @7.1.0 +qt5 +qt4: incorrect dependencies

[petrrr]

Hi, when trying to install vtk with the above mentioned variants, I get the following error message:

petr% sudo port -v config vtk +qt5 +qt4
--->  Computing dependencies for vtk.
Error: Dependency 'qt4-qtbase' not found.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.
Error: Processing of port vtk failed

Well, possibly these variants are mutually exclusive, but then this condition should be handled. Otherwise, if they could coexist, the dependency need to be set correctly. See below:

petr% sudo port -v info vtk +qt4 +qt5
vtk @7.1.0 (graphics, devel)
Variants:             debug, [+]python27, python35, +qt4, +qt5, universal

This presumably occurs in the qt5 Portgroup.

I uploaded a patch to set conflicts between qt4 and qt5. It also updates to 7.1.1 and adds python36 variant.

Looks like this was fixed, so can this be closed?

vtk: drop qt4 variant

VTK 8.2.0 removed support for Qt4.
