Сервис Mindtouch dekiwiki аварийно завершает работу при запуске (ошибка отсутствующей сборки)

Это новая установка Mindtouch Core в Ubuntu 10.04. Я слежу за Инструкция по установке на сайте сообщества Mindtouch.

Когда я пытаюсь запустить сервис dekiwiki, он вылетает со следующей ошибкой:

** (/var/www/dekiwiki/bin/mindtouch.host.exe:14465): WARNING **: The following assembly referenced from /var/www/dekiwiki/bin/mindtouch.core.dll could not be loaded:

Я дважды проверил, у меня установлен Mono 2.10 и сборка System.Web.Routing определенно присутствует, Mindtouch ее просто не находит.

Любые идеи?
