Bug#773424: tcl-vtk6 is unusable

[Mathieu Malaterre]

Package: tcl-vtk6
Version: 6.1.0+dfsg2-4
Severity: grave

This is not clear how one should use tcl-vtk6, it does not provide the
wish interpreter anymore (aka `vtk` runtime binary). I do not believe
the package is usable by anyone.

If I build vtk6 package locally and execute it:

$ sudo apt-get install tcl-vtk6 vtk6-examples
$ apt-get source vtk6
$ dpkg-buildpackage -rfakeroot -us -uc
$ ./debian/build/bin/vtk
/usr/share/doc/vtk6-examples/examples/Examples/Tutorial/Step2/Tcl/Cone2.tcl
