Hmm, OK. I've no problem with that (although I do find the packaging guide pretty hard to get into for an end user who only wants to *use* packages, not *create* them

there's a section marked "Installation Tutorial".  Someone wanting to install packages should be able to get into that, once it actually has content  : )
 
I think we should explain *in the core documentation*  
How about if I provide a new (short) document called something like "Python package management"

IMO, we should put the energy into one comprehensive document (the new user guide) and link out to it, not duplicate effort into the core docs.
The "Installing Python Modules"/"Distributing Python Modules" documents should be integrated into the new User Guide.  
It will be confusing and anti-zen for a user to come upon those documents and have to reconcile it with the user guide
