Pidgin doesn't connect to network with networkmanager-0.9 I think the nm-0.9 connection states are missing: http://developer.pidgin.im/ticket/13859 is it possible to add this to the in tree version of pidgin?
If it is not possible to add this please add networkmanager? ( =net-misc/networkmanager-0.8* ) to the ebuild.
networkmanager-0.9 works with newer versions of pidgin
