 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

 This presumably occurs in the qt5 Portgroup.
