I just read the documentation and tried to use it.

Distribute a Python package on Windows.
Suppose package A depends on pure Python package B and on PyQT.
Right now I have two options:
1) create an installer using PyInstaller or py2exe
2) have the user install Python (not a problem), PyQt
(the "all included" installer) and then easy_install my application
I think this is a big problem.
Even if we assume that it is ok to create a PyInstaller installer, I
don't see why a Windows user must not be able to do:
and have B and PyQt (with external libraries) correctly installed on the
eggbuild tries to solve this problem.
It build eggs that "embeds" all required shared libraries (excluding
shared libraries already required by the Python interpreter -- this
usually allow me to forget about SxS mess with Visual Studio

I have never used zc.buildout; however, as I wrote, what I'm trying to
do is to solve the "external libraries" problem using standard eggs.
Building an all included installer its the second step.
For me it's already good if easy_install is able to install binary eggs
with external libraries embedded!
