So don't do that.  Plone is an application (afaik) not a library.  I  
thought Plone had an installer that installed a local Python.

Cool. Note that I think this problem will get worse as system  
packages include more and more of the packages we use. I read  
yesterday that the Python in Mac OS X Leopard includes zope.interface.

This is really a separate issue.  I hope we won't either.  
Unfortunately, supporting them is non-trivial,  I think we've made a  
lot of progress.

I don't agree. easy_install is really not well suited to installing  
applications IMO.  I think an installer is a better idea for  
installing applications, for lots of reasons.
