[Therion] MacOS install issues: version conflict for package "Tk": have 9.0.3, need 8.1.1

[Rodrigo Severo]

Hi,

I am trying to help a friend install Therion in a Mac. After following the instructions available at https://github.com/ladislavb/homebrew-therion, when trying to run xtherion as instructed we are getting the following error:
% xtherion
Error in startup script: version conflict for package "Tk": have 9.0.3, need 8.1.1
while executing
"package require Tk 8.1.1"
("package ifneeded BWidget 1.9.1" script)
invoked from within
"package require BWidget"
(file "/opt/homebrew/bin/xtherion" line 12915)

I have already applied the TK version and BWidget fixes mentioned at https://github.com/ladislavb/homebrew-therion but the issue remains.

Any ideas?

Regards,

Rodrigo
