If you have not used virtualenv or buildout your eggs are probably weirded out.
x64 had issues at the time for me on different environments.
Where you installed Python
I used /work/piano
If there is no bootstrap.py file then use WGET to fetch it.
wget http://svn.zope.org/checkout/zc.buildout/trunk/bootstrap/bootstrap.py
python bootstrap.py
Warning
Press <ENTER> after a seeing the buildout script is generated (don’t know why this hangs but been like that forever on Windows).
After running the buildout command for the first time you only need to run it again when dependencies change.
Note
You only need to do this when you first setup your environment.
