I get it. Thank you. It is the old tool-upgrade-breaks-lots-of-things scenario. Using the upstream numpy instead of my locally built, later version, means that it found and is trying to link to something old. I need to read out the -L arguments and see where it went askew. In the meantime, before your response, I am trying a git pull, in case someone managed to update the code.
