Thanks IOhannes! Which distro does pack these snapshots? On Debian I see
the following: https://packages.debian.org/bookworm/gem
No distro package needed.
Have you used deken? It's a packaging tool that comes with puredata.
From the main puredata window go to 'Help' and select 'Find externals'.
It's not obvious. But from there you can get all of the libraries and they will be installed in your user directory instead of the root dir on Linux.
