Thanks. The version in the pastebin linked worked fine, ish. Rpm complains about a missing freetype module. However, installing the produced .rpm file through Yast2, works if allowing the installer to "break" the application and ignore this dependence. This works fine if freetype2 is installed or available (which it is in the current Thumbleweed version at least). When trying to install the .rpm from the command prompt, I got some other errors (that I neglected to keep), but these did not show when using Yast2.
1.3.5 (10/19/2024)
1. SUSE automatically defaults to --install=local
2. RPMs build properly for <= MC31 that lack the MC stub
3. No MC latest version check is performed when only using --install=repo (faster, relies on package manager to identify latest version)
4. Added --no-update option to disable installJRMC self-updates
