New comment by tornaria on void-packages repository https://github.com/void-linux/void-packages/issues/47683#issuecomment-1849171543 Comment: Install `meson` and try again. It's now required by `numpy.f2py` but not listed as a depends neither to numpy nor sagemath. You'll see it's listed in checkdepends for both. What do you think we should do? Add `meson` to sagemath depends? It's not really necessary unless one needs to use fortran code in sage. OTOH we have `gcc-fortran` as a dependency, so I guess either we add meson or we remove gcc-fortran. Ideally there would be a "feature" that checks whether f2py is available and working, and then all doctests that depend on this are labeled "# needs fortran" or something like that.
