Luis Eduardo Villares Matta commented on CASSANDRA-2989:
--------------------------------------------------------
Please note that I am using Debian packaging.
JNA is a requirement of the package, and I checked that it is there.
So the fact that it is not using it might be a packaging (building, linking)
error (or one of my own :)
