I have managed to install Octave 3.8.0 now on Ubuntu 13.10 x64. The 
solution was 1) to remove the JAVA_HOME definition and allow Octave to 
sort out defaults never mind warnings and 2) I had sudo make install.

I have installed the packages that I need, but Octave crash with a 
segmentation fault, even with a simple plot like sin(x), see details below
