It's possible that there could be a *version* of Sage with them, if they all worked well. There's no technical reason why one couldn't do that at all. It's completely a matter of willpower and effort. > Let's say I need SPD + another 10 packages. Downloading each of them > by hand with "./sage -i" is boring.
