render as Rst one step ahead (maybe...)

ok, From this page 
http://www.merten-home.de/FreeSoftware/moin2rst/manual.html#installation,
I've found the doc and the file to use, to obtain rst.

- I've downloaded it
- extracted
- putted on .../plugin/action and formatter folder
- restarted apache2
- login to my wiki
- create a page
- went to action menu
but no action render as restructured text found :-(

the Renderasrestructuredtext.py has root:root right. Could it be this 
the prob?

TIA

Renato
