Error after enabling zimbraDrive 0.0.1 app

[Phangorn]

server : owncloud 9.0.8 on ubuntu 14.04.5

After installing the app in owncloud and enabled it I don't have the zimbra drive option in the admin panel.

in the log I found this error :

Exception: {"Exception":"OCP\\AppFramework\\QueryException","Message":"Could not resolve OCA\\ZimbraDrive\\Controller\\PageController! Class OCA\\ZimbraDrive\\Controller\\PageController does not exist","Code":0,"Trace":"#0 \/var\/www\/html\/lib\/private\/appframework\/utility\/simplecontainer.php(104): OC\\AppFramework\\Utility\\SimpleContainer->resolve('OCA\\ZimbraDrive...')\n#1 \/var\/www\/html\/lib\/private\/appframework\/app.php(97): OC\\AppFramework\\Utility\\SimpleContainer->query('OCA\\ZimbraDrive...')\n#2 \/var\/www\/html\/lib\/private\/appframework\/routing\/routeactionhandler.php(45): OC\\AppFramework\\App::main('PageController', 'index', Object(OC\\AppFramework\\DependencyInjection\\DIContainer), Array)\n#3 [internal function]: OC\\AppFramework\\routing\\RouteActionHandler->__invoke(Array)\n#4 \/var\/www\/html\/lib\/private\/route\/router.php(276): call_user_func(Object(OC\\AppFramework\\routing\\RouteActionHandler), Array)\n#5 \/var\/www\/html\/lib\/base.php(907): OC\\Route\\Router->match('\/apps\/zimbradri...')\n#6 \/var\/www\/html\/index.php(47): OC::handleRequest()\n#7 {main}","File":"\/var\/www\/html\/lib\/private\/appframework\/utility\/simplecontainer.php","Line":89}

probably a missing dependency but i can't figure which one ...

any help ?
