Thanks! I should have mentioned that it comes from the log file 30-coot.txt, which I preferred not to attach since it contains in many places host names and environment variables that shouldn't get published. If you need it for debugging, I'm happy to email it off-list.
For completeness, we are using CentOS 7.9 (revision 2009): hopefully there are no difference from 7.6 affecting the build. I'll give it another try with an Ubuntu 20.04 container. I already need to use that workaround for other structural bioinformatics tools unfortunately.
