Ok, that explains it... I was curious and digging through how you managed to get that working.
Try to run the update from your dashboard and see if it addresses your issue, also do the uninstall/reinstall for good measure. It's possible there may be a dependencies issue, I will need to run through that for good measure on a Debian 7 install.
Additionally, feel free to throw me you server details via PM and I will login and take a look.
