I ran into this same problem when trying to use the instructions on the download page to upgrade from 4.0beta to "Latest 4.0". pvedaemon would throw this error when I tried to run it (which caused the config step of pve-manager to fail. Somehow, not all of the PVE packages and libraries were getting updated. Eventually, what I had to do is get the Proxmox 4.1 ISO file, extract everything matching "proxmox/packages/pve-*.deb" from the ISO, and then I used "dpkg --install pve-*.deb" to install them all at once.
