Kpackage requires the smart package manager to be installed and once it is installed it does not work fully with slackware packages, however it is easy to install packages.
Code:
installpkg wine-1.1.24-i486-1kjz.tgz
as root from the command line in any terminal or terminal emulator.
However you may wish to investigate sbopkg as it will download, compile and install packages for you, and also manage upgrades.
