By the looks of it - correct me if I'm wrong - there is work being done 
on zc.buildout that changes the default behavior regarding isolation 
from the system python's site-packages.

Current default behavior is to generate paths and scripts that are 
isolated. The default behavior will be - again, correct me if I'm wrong 
- to not isolate from system python, unless explicitly told otherwise.

This means, if we really want to support system python isolation for 
projects created with grokproject, we'd have to generate a buildout.cfg 
for these projects that explicitly configures the project to not include 
system python site-packages. In other words, if we use the respective 
directives explicitly in the generated buildout.cfg, we can safely 
upgrade from 1.5.1 to zc.buildout-1.5.2 in the future without a sudden 
change in behavior.
