I plan to install Chinese in bt4
I am at KDE Control Module and whenever I click install new language, it tells me that:

KDE su
Command 'qt-language-selector --mode install' not found

I tried apt-get install qt-language-selector but this is the output:
root@bt:~# apt-get install qt-language-selector
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package qt-language-selector

Also, ubuntu intrepid uses ibus for international language support.
Does bt4 have a similar application?
