[Therion] Therion fails on Fedora 41

[Bill Gee]

Hello everyone - I have upgraded one of my test machines to Fedora 41. 
Therion 6.2.0 now fails to run with a complaint that libfmt.so.10 cannot 
be found.  Very true!  The fmt package was upgraded to version 11 and 
the shared library is now libfmt.so.11.

I downloaded the latest source code for version 6.2.1 and went to 
compile it.  The compile fails, and I think it is related to fmt.  The 
last few lines from the compile run are listed below.

How can I get past this?

Thanks!
