i believe the www.mepislovers.org
website has instructions on how to upgrade kde. personally i can hardly tell the difference....
as for super karamaba, i installed some libraries and stuff and then compiled it.
you could download the source. unzip it.
you'll get some errors, but you can search for them. i did and got it compiled ok. i think i had to installed something like kde-base-dev or something.... sorry that i can't be more specific, i've deleted that install now.
