Can you run tca_correct from a terminal? That's the only part of hugin needed 
by the script, AFAIK. If you can, then the package is probably installed ok, 
and the issue is with the script.

I can't help with the Mac paths, but there was some work done on the script to 
get it running on Windows, still lingering in a PR here: 
https://github.com/lensfun/lensfun/pull/291

Diffing that with the old version might give you a good idea of where paths 
would need to be changed for a Mac environment; I'm not aware of anyone trying 
to do this previously.

Ultimately, the script is really only *essential* for vignetting correction, 
but it does make running tca_correct on multiple files and inserting the values 
into the profile more convenient than using it manually. I often end up making 
the corrections manually in darktable anyway while checking the results of 
tca_correct, YMMV.
