Shared directories can now be created independently by the pacakges
needing them and will be removed automatically by pkg_delete when empty.
Packages needing empty directories can use the @pkgdir command in PLIST.

PolicyKit is an application-level toolkit for defining and handling the
policy that allows unprivileged processes to speak to privileged processes:
It is a framework for centralizing the decision making process with respect
to granting access to privileged operations for unprivileged applications.
PolicyKit is specifically targeting applications in rich desktop environments
on multi-user UNIX-like operating systems. It does not imply or rely on any
exotic kernel features.
This package provides a D-Bus session bus service for bringing up
authentication dialogs used for obtaining privileges.
