Xubuntu doesn't pull required dependencies for anything using "Online Accounts"

I installed things like Gwibber, and Shotwell, and they all depend on the "Online Accounts" functions of Unity in order to sign on to online services like Facebook and Twitter. In Xubuntu, when installing and launching these packages, there is no way to add any online accounts, because the required sections for Online Accounts are not present. Gnome Control Center got pulled in, but the Online Accounds applet is missing from within. Also, pulling in these apps pulled in a few Gnome dependencies, which killed xfce4-power-manager. (Now my battery icon is missing on the laptop and sleep functions don't work). Launching it manually states there is already another power management app running.
