Thank you for this tip, I managed to successfully compile it this way. I had to do 'cd .' before cmake command, and finish off with 'make install' to place the apps at the correct location. It still produced a few errors in Loch sections, but the program seems to run OK in the end. The errors:

For those having problems with tcl/tk versions, there is a section at homebrew-therion mentioning this problem: https://github.com/ladislavb/homebrew-therion?tab=readme-ov-file#xtherion---cant-find-package-bwidget

Trying using cmake, I find it does a better job at finding dependencies:

    cd therion
    cmake -S . -B build
    cd build
    make
