[Therion] macOS installation

A recent brew update/brew upgrade seems to break my Therion install again.
The library in question is 'fmt' which was upgraded from v11 to v12
apparently. If I try to compile anything with therion, I get the
following error:

dyld[13602]: Library not loaded: /opt/homebrew/opt/fmt/lib/libfmt.11.dylib

  Referenced from: <1DDE563D-8CCA-3795-BBC8-F76B62F9AE43>
/usr/local/bin/therion

  Reason: tried: '/opt/homebrew/opt/fmt/lib/libfmt.11.dylib' (no such
file),
'/System/Volumes/Preboot/Cryptexes/OS/opt/homebrew/opt/fmt/lib/libfmt.11.dylib'
(no such file), '/opt/homebrew/opt/fmt/lib/libfmt.11.dylib' (no such file),
'/opt/homebrew/Cellar/fmt/12.1.0/lib/libfmt.11.dylib' (no such file),
'/System/Volumes/Preboot/Cryptexes/OS/opt/homebrew/Cellar/fmt/12.1.0/lib/libfmt.11.dylib'
(no such file), '/opt/homebrew/Cellar/fmt/12.1.0/lib/libfmt.11.dylib' (no
such file)

zsh: abort      therion



Do you recommend I look at trying to install the v11 again (brew install
fmt at 11.2.0 doesn't work) or does this need to be addressed by therion
developers?

Thanks in advance,
Anze
