[TIP] Dependencies installation order with Tox

[holger krekel]

Hi Aaron,

if you simply do:

    virtualenv --distribute --no-site-packages -p /sw/bin/python2.5 py25
    py25/bin/pip install numpy scipy

does it work?  If so, can you remove .tox (to remove the download cache)
and re-invoke it?

best,
holger
