[Users] McLachlan code generation working in current stable ET release?

[Bernard Kelly]

Hi. I'm trying to regenerate the McLachlan ML_BSSN thorn by running the
Mathematica-based scripts on my Macbook. The process is failing, and I'd
like to know if it's an issue with my Mathematica installation or the
McLachlan code?

I have a pretty up-to-date Mathematica -- v 12.2 for Mac. For simplicity, I
didn't do a general "make", but chose a specific thorn. Here's what happens
if I try to run the script from inside the McLachlan/m directory.

Any suggestions appreciated -- but please don't ask me to go to an earlier
Mathematica version!.

Bernard
