Rolf,
Glad you're sorted out, and I concur in the thanks to Ivan (and Johannes and other who patiently helped). To me, the take-away message is that /usr/local wins generally, not just in your $PATH (or, say, in R's library path) but also for configure and friends so ... it opens the door for shooting both your feet off. And I concur on 'fervent devotee of the "sudo apt-get install" paradigm' as that is better and cleaner. And allows uninstalling ! As mentioned, Docker is also good. Read up on it. It makes for a /great/ way to experiment without side effects. You can install (and run, and if you want persist in a container) things while leaving your outer system alone. Lots of tutorials out there.
