[Pharo-project] how can I use Nautilus with OCompletion?

I just took the Nautilus from jenkins, installed OCompletion there and OCompletion seems to work fine everywhere in the image but not in Nautilus. In the code pane...it doesn't appear anything. So...is there a way to make OCompletion to work with Nautilus? Thanks! -- Mariano http://marianopeck.wordpress.com
