wish - tcl/tk on Build 117 does not work correct

On OpenSolaris - Build 117, the tcl/tk wish installation does not work.
The program secpanel ( a GUI for ssh management ) does not work.
Starting wish on a commandline issues the following error:

bash-3.2$ wish
Application initialization failed: Can't find a usable tk.tcl in the following directories:

This probably means that tk wasn't installed properly.

Something with the installation during the upgrade must have failed.
