I suspect there's more than one. ;)

I generally don't bother setting up private PyPI servers -- dropping the
.tar.gz files of private package sdists in a directory and exporting it
with Apache (with password protection if you wish) works just fine.

There's generally a single version control checkout that contains the
buildout configuration (with find-links = https://private-package-page-url)
and the main app.  I also use buildout-versions to ensure all the
dependencies have version pins to avoid unpleasant surprises on
deployments.

Sometimes unpleasant surprises still happen, when an
upstream package sdist disappears off the net and I have to go hunt it
down from someone's buildout cache and drop it into the same private
package page.
