Hello once more. I only wanted to know whether there is a way to cause automatic python3 module rebuilds after a python3 update. If i do $ prt-get dependent python3 doxygen nftables python3-setuptools python3-flit-core xorg-xcb-proto that isn't it. However, after updating python (only about 30 MB instead of whatever i said last, iirc something over 50, thank you), the mesa compile failed, because python3-pyyaml and then -mako then -markupsafe where no longer usable by the mesa build. I never used pip3 before, but .. i cannot seem to find anything that would be right for the task there. Now i wonder whether a combination of find /usr/lib/pythonXXXX/site-packages -maxdepth 1 -type d and pkginfo -o would do what i need? (Or can't we skip compilation during build, so that the pycache directories do not exist? Or .. ??) Thanks for any hint, a nice Sunday i wish from Germany, --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt)
