pip and distutils

[Vraj Mohan]

I have created a source distribution using distutils which specifies
external packages using:

setup(
...,
requires = ['Foo (>= 0.7)', 'Bar (>= 2.4.5)'],
...
)

When I use pip to install this distribution, I find that it does not
automatically install the packages Foo and Bar. What extra step do I
need to perform to have pip automatically install the "required"
packages?

I am using Python 3.2.3.
