:blush:

While looking at what I'd need to do to clear things down and start 
again from scratch, I spotted that I had downloaded openssl_1.1.1 myself 
in January 2023. Buoyed by this discovery, I did

make uninstall

from the openssl_1.1.1 download directory, then started again with 
tcltls 2.0b1, which... compiled and linked with no problem.

Many, many thanks to Ralf, Brian and Ashok.
