Apparently I now SageMath doesn't work anymore. If I try to start the
Jupyter kernel for Sage
I now get errors about libntl.so.33 (see the log file attached).
Something I found confusing was why ntl and python even, were built
throughout the installation
of polymake. Those two (ntl,python) were already available.
