[Tutor] dependencies

[Jim Mooney]

I downloaded scipy for 3.3, installed numpy first, ran setup.py, but
now I get this error:  Blas (http://www.netlib.org/blas/) libraries
not found.

Okay, I went to the scipy site, but it doesn't say a thing about this
dependency. Am I missing something? Shouldn't these packages tell you
what all the dependencies are so you don't just flail around? Or are
they somewhere I'm not looking?

I'm looking at the scipy page:
https://pypi.python.org/pypi/scipy/0.12.0 and don't see a thing about
Blas.

Is there something obvious I'm supposed to know that I've missed,
regarding installs? At my level they seem to be a confusing mess.
