kde 3.4.1

[Nando Debian]

 Hi I install Debian sarge today and upgraded for unstable, but I
can't install kde 3.4.1 here.
 
 In my sources.list I added line:
 
 deb http://pkg-kde.alioth.debian.org/kde-3.4.1/ ./
 
 and when I put aptitude update, I get one error:
 
 Ign http://pkg-kde.alioth.debian.org ./ Packages
 
 what I need to install?
