Because TurboGears by itself doesn't depend on those, installing only the
TurboGears2 package it's much like installing flask, you get only a
framework without caching, sessions, auth, template engine and so on...
It's much like a micro-framework. Then, for example, in case you add a
"session.enabled = true" option you will need Beaker so you will have to
add it to the dependencies of your project. By default when you quickstart
a new application all those dependencies are added for you depending on the
quickstart options (for example if you enabled database or not).

As I copied the app_cfg.py file from and app that used
authentication/authorization repoze.who is a dependency even though
Kallithea doesn't use it. But I have been too lazy to disable it :P

To try it I copied an already existing kallithea.db from a production
environment, so you probably ended up in a code path that my configuration
didn't trigger :(
As I don't know much about Kallithea codebase I just fixed issues as they
arose until I saw the homepage working, so I'm sure there are many things
that still don't work.

I don't know if it matters but when I tried it I logged as the admin as my
configuration required login, that probably sent me to a different menu
layout or code path that didn't face that issue.
