my first tests show that this version indeed works (at least on Catalina).
could someone on Big Sur or Monterey confirm this?


PS: here's a bit more in-depth tech babble, for those interested what (I 
think) is going on:

i now think that this was a red hering.

the problem really seems to be that depending on whether Pd is linked 
against  JACK from homebrew or jackaudio.org it will look for the 
library in /usr/local/opt/jack/lib/ resp. /usr/local/lib/.
for reasons i do not fully understand yet, a homebrew-jacked Pd (that 
looks for libjack.so.0.1.0 in /usr/local/opt/jack/lib/) will refuse to 
load the library if it is found in /usr/local/lib/ (even though this is 
a standard search path for libraries).
copying/symlinking the libjack.so to the searched for directory, makes 
binaries work.

$ mkdir /usr/local/opt/jack/lib/
$ ln -s /usr/local/lib/libjack.0.1.0.dylib /usr/local/opt/jack/lib/

of course this is not really practical
