The stable version is updated to 2.2.4
deb
http://www.vollstreckernet.de/debian/ stable amule-stable wx upnp
wx and upnp are empty for now, because the current stable debian has everything needed in it's original repositories. When the are needed, the get filled, so for now you can ommit them, but maybe you'll need them latere.
For sure, you can get the sources for selfcompile the usual way via:
deb-src
http://www.vollstreckernet.de/debian/ stable amule-stable wx upnp
You can combine those two possibilities to get just what you want.
