Choqok seems to be about the only native microblogging client for KDE. It's actually a rather nice app, but I've found it to be rather buggy when it comes to Twitter authentication. For the last few months it has moaned about not being able to authenticate, after which it crashes. Starting the app again does the same thing, which means it crashes constantly, and you're left without a Twitter client.
Perl has CPAN, Ubuntu and Debian have apt/debs, Gentoo has portage. These are all various distribution or packaging systems, which allow you to download and install packages from the various systems fairly easily. Of course Python also has it's own system.
