Thank you for your answer Jochen,
Now working also with the latest library version :-)
Following your confirmation "NEST does not actually specify a specific library
version" I restarted a completely fresh installation removing not only the build
directory for the sources but also any nest related file in my ~/.local installation
directory. After now compilation and installation all tests pass now and pynest can be
I suppose there was and interference with preexisting files and paths. Clean build
directory wasn't enough and deep clean in installation folder sokved it.
Thank you for the fantastic work and support.
