Hi Clemens, Thanks for the report. The issue with the dependencies of the packages was discussed, and adding a dependency for a demo was not welcomed. So, I will fix the demo to use text_waitbar only if miscellaneous is loaded. @everyone: Would that be ok? Regarding lapack, I do not know what to say. I assume user will get the latest/fixed version (?). Thanks again. -- M. Sc.
