Ah, but to me this is the moral equivalent of:

    wget random-install-script-url | sh

Ideally I'd be doing the install, and arguably the build, as a third 
user, neither root (keep the system intact) nor myself (my data! mine!  
don't you touch it!)

Aye.

But they seemed to be on the route of installing over the system Python, 
and I was trying to talk them down to just a "system wide but off to the 
side" install.
