thank you. I am starting to grasp the "behind the scenes"... However, I stillave problems in operationalizing it: in the module documentation I read:

Second method

Copy installed Tcl/Tk binaries to some location, then install Perl mod
+ule Tcl
with a special action to make Tcl.pm know of this location. This appro
+ach
makes sure that only chosen Tcl installation is used.

No mention however how to accomplish it. Google doesn't help too. I am surely not very fit in this kind of things, but a bit more documentation would help. So, I again would very much appreciate any suggestion
