I found the problem to be a rogue service file that was installed to: /usr/local/share/dbus-1/system-services/org.freedesktop.PolicyKit1.service which had a Exec=/usr/local/libexec/polkitd which doesn't exist. This service file was clobbering the one in: /usr/share/dbus-1/system-services/org.freedesktop.PolicyKit1.service which had a correct Exec path. I'm not sure how this got on my system but the problem occurred after an update. Deleting the file in /usr/local/share/dbus-1 fixed all the problems I was seeing.
