Scribus 22.214.171.124 is in the VL repository under /extra. You may have to add that directory to your /etc/slapt-get/slapt-getrc file. As root add this line:
Then run gslapt, search for Scribus, and have gslapt install it.
Scribus 126.96.36.199 is not the latest version. The latest stable version is 188.8.131.52, which is not in our repositories. You can download a package for 184.108.40.206 from linuxpackages.net, but I don't know how it handles dependencies. Or you can compile 220.127.116.11 from source code.
