distribute's "PKG-INFO" doesn't mention setuptools, since its fields are:

...
name: Distribute
version: 0.6
...

So when pip or easy_install are asked to install "setuptools" they
will both look for a PKG-INFO
containing:

...
name: setuptools
...

Yes I am defending the faked PKG-INFO which contains "setuptools" in
the name field,
and 0.6c9 in the version one. For practical reasons its' not a
PKG-INFO I am installing
when Distribute is installed. But in a bootstrap process.

So distribute setup.py file looks like ths:

before_install()
setup(...)
after_install()

and the same code is used by the boostrapping module that replaces ez_setup.py
(which is going to be named in something else after chris feedback)
