Bugzilla Bug 234965

gitk and hgk fail with =dev-lang/tk-8.4.18, I haven't tested against lower
versions, but masked version doesn't work either. hgk fails completely, gitk
start up, but menu doesn't work. They produce this output:

This probably means that tk wasn't installed properly.

Reproducible: Always

i discovered that aswell with gitk and app-text/ding
