I've discovered that also...

The problem is Ubuntu itself, some links are missing with native libraries.  
For example, libgstreamer-0.10.so is normally a link to 
libgstreamer-0.10.so.1.0.1 (or something like that.  

In 11.10, those link are not there and JNA.jar cannot find the library.  Still 
investigating why this is happening
