I described the problems I had trying to follow that advice.

In article <mailman.425.1376137459.1251.python-list@python.org>,

That really kind of proves my point.  It's *not* easy to install.  
Theres' a choice of methods, some of which work in some environments, 
some of which work in others.  And even if apt-get is the preferred 
install method on Ubuntu, it's a method which is unavailable to people 
without root access (and may be undesirable if you rely on virtualenv to 
keep multiple projects cleanly separated).

And, what happens if you don't have the right libraries?  Do you end up 
with an install which is missing some functionality, or one where all 
the calls work, but they're slower, or numerically unstable, or what?

All these questions go away if it's packaged with the standard library.

I'm not sure where the line should be drawn between "basic stuff that 
should be included" and "advanced stuff that you need an add-on to get", 
but certainly mean and std-dev should be in the default distribution.
