I looked into this further and found that this actually seems to be a 
limitation of the Java System.loadLibary() call (I have no Java skills 
so please correct me if I'm wrong) used in:
src/libbluray/bdj/java/org/videolan/BDJLoader.java

It seems that System.loadLibary() only looks for 'libname.so', there 
doesn't seem to be a way to make it look for 'libname.so.$major' as 
would be more correct.

I guess for packaging libbluray that means that the libbluray.so link 
has to be included in the libbluray RPM rather than the libbluray-devel 
RPM.
