Hello there. I was wondering if anybody knew what is causing this compilation error I'm getting on a new Ubuntu 14.04 VM with a 3.13.0 kernel.  It does not find the DEBIAN_API_VERSION symbol. The use of that was introduced in 2.6.1 apparently:

I'm following the instructions in the Download page to install from the PPA :  http://lttng.org/download/#ubuntu

This the error I'm getting. Thanks in advance for any help!
