[TIP] Dependencies installation order with Tox

No, it does not.  I get

Downloading/unpacking scipy
  Downloading scipy-0.9.0.zip (7.6Mb): 7.6Mb downloaded
  Running setup.py egg_info for package scipy
    Traceback (most recent call last):

      File "/Users/aaronmeurer/Desktop/py25/build/scipy/setup.py",

        from numpy.distutils.core import setup
    ImportError: No module named numpy.distutils.core
    Complete output from command python setup.py egg_info:

----------------------------------------
Command python setup.py egg_info failed with error code 1
Storing complete log in /Users/aaronmeurer/.pip/pip.log

which is basically the same error that tox gave me.  But if I do

py25/bin/pip install numpy
py25/bin/pip install scipy

it works (actually, scipy exits with a compiler error, but I think I
can fix that by making it compile an older version, and anyway it's
unrelated).

I know almost nothing about how this stuff works, but if I had to
guess, I'd say scipy isn't listing numpy as a dependency correctly.
The question is, why does pip insist on installing scipy first, even
when it is given second?
