Any suggestion on this topic? I tried many options... error in the last three lines

Looks like

tcl

is not installed (although

tk

is).

I tried to install tcl, and the installation is done without any errors. 🥲 I spent all my weekend to install this tons of system

Ahh. Do the tcl and tk versions match?

tk8.6 and tcl8.6. is there a specific command to verify the installed version?

you need to install the -dev packages for tcl and tk:

tcl8.6-dev, tk8.6-dev

the list of dependencies is here

I re-installed both. now it is works!
