aMSN SVN (Linux Ubuntu) precompiled packages. deb
Even if all packages are compiled into the repository automatically shown in this article, for those who want to download the latest version and do not know / want to compile from svn, I prepared a script that, when there is a new version, allows you to compile and Uppa automatically on my server.
If you are interested, You can download it from http://nix.flapane.com folder Ubuntu.
update: From today, 26 April 2012, aMSN is compiled on Ubuntu 12.04 and no longer on 11.10. It was also added support for libfarstream for audio and video calls!

By way of example here it is in operation with the skin WLM live:
