Thanks Jim. That answers a lot of questions. Apparently Fedora 42 is
too close to the cutting edge.
I downloaded the tarball for Img version 2.1 and took a stab at
compiling it. Fail - I do not have a file named tclConfig.SH on my system.
bgee@main2:~/Installs/Img-2.1.0$ ./configure
checking TEA configuration... ok (TEA 3.13)
configure: configuring Img 2.1.0
checking system version... Linux-6.15.9-201.fc42.x86_64
checking for Tcl configuration... configure: error: Can't find Tcl
configuration definitions. Use --with-tcl to specify a directory
containing tclConfig.sh
bgee@main2:~/Installs/Img-2.1.0$ locate tclConfig.sh
bgee@main2:~/Installs/Img-2.1.0$
In the meantime - The workaround I found is working. Eventually someone
will probably do a new tkImg package for Fedora 42.

According to https://wiki.tcl-lang.org/page/Img <https://wiki.tcl-
lang.org/page/Img>, version 1.4.16 is not compatible with tcl9, and
version 2.1.0 (or later) is required.
Cheers,

Hi Bill,
Can you please try to run XTherion on a new installation of Fedora 42,
for example in a virtual machine? I see that Fedora 41 has tcl 8.6,
and Fedora 42 has tcl 9, so maybe this is a leftover from a system
upgrade. Also please note that after OS upgrade you need to do a clean
rebuild of Therion, because libraries in different OS versions are
usually not binary compatible.
