That's fine, buildout can use a shared eggs directory (it's how I run it 
by default, to minimise the amount of downloading that goes on). In that 
case, there would be no duplication of packages, the "installed app" 
would just pick from a folder full of eggs that you could put wherever 
your OS wants them...

In short, have multiple versions of a python package on the python path 
at the same time is insane ;-)
