Hi Mark, many thanks for your explanations. You may remember from here: https://lists.gnu.org/archive/html/guile-user/2019-08/msg00016.html that I'm used to switch guile-versions pretty frequently. For every guile-version so far 'sudo make install' worked out of the box (apart from the problem discussed in the linked thread), thus I was surprised it didn't today. Thanks, Harm
