Koffice 1.2.1 and libarts1-qt

[alessandro <masacar@virgilio.it>]

hi, anyone knows where i can find a working apt-source which contains 
libarts1-qt package to install the latest release of kde and koffice?
when i do "apt-get install koffice" i found a dependency problem whith 
the libraries libarts1-qt and the same getting kdesdk which wants 
libarts1-qt-dev.
Anyone knows a complete apt-source to solve my dependency problem or 
knows another way to upgrade all koffice and kde?
