[Seaside] Under Pharo 3 how to see the Seaside Control Panel ?

[Rene Mages (ramix)]

Hello seasiders,

Under Ubuntu 13.04 my apache2 is perfectly responding (port 8080) but
nothing visible has happened when I have evaluated in a  workspace :
       ZnZincServerAdaptor startOn: 8080
I have checked that Zinc package is present in my pharo image ( I am
running Pharo 3 ) :

When I follow step by step the directives of this page :
       http://www.seaside.st/download/pharo
in particular :
  Starting the Zinc Web Server
      Open the ’Seaside Control Panel’ in the ’Tools’ submenu of the
’World’ menu
I can't see the Seaside Control Panel in the submenu 'Tools' :

Thx for your help
