Directory for Unopkg on OOo 3.4 Ubuntu

[daviding]

I have a message panel from "Zotero OpenOffice.org/NeoOffice/LibreOffice Integration Installation", that is coming from Firefox 13.0.1 under Ubuntu 10.04.

> Select OpenOffice.org/NeoOffice/LibreOffice unopkg executable.
> Select OpenOffice.org/NeoOffice/LibreOffice installations from the list below, or check "Add Installation" to locate the pat to an OpenOffice.org installation directory not shown on the list below.

I have a a check beside the directory /opt/openoffice.org3/program/unopkg .

I notice that there's another directory /opt/openoffice.org/basis3.4/program/ , but there I don't see an unopkg directory there. I do see uno.py .

When I start OpenOffice, under extensions, I have "Zotero LibreOffice Integration 3.5.3" with "Error: The status of this extension is unknown".

Am I missing a directory for unopkg, or should I install somewhere else?
