If you ever wanted to set up a Sage non-profit (if you didn't already)
it might be easy to do it now.
(But my hunch is that NumFOCUS is happy to tunnel through donations to
Sage as part of their own operation too, so it's probably no reason to
do it. Just in case.)

I just stumbled over Gentoo prefix -- have any of you tried it out?
In short, it allows a Gentoo Linux system in a subdirectory, on Linux,
Mac, Windows/SUA, Solaris. Gentoo is thus awfully similar to the Sage
spkg system:
- Installs Unix software in a common prefix location.
