Using a search block in ezflow generates an error
Module not found (see attached image)

Note: This installation is not running the very latest version due to the problems on hudson. It is running a version from a few days before hudson died

Steps to reproduce

Install an ezpublish with ezflow/ezfind extension
Create some content (ex: A folder and an article)
Edit frontpage and add a Search Block
Search for any word and press "Search" on this block
