The Tomcat native library is a performance option. To use it, you have to do a custom build of Tomcat.
Usually it's not worth the trouble. My opinion on the matter is that if you are so close to the limits on capacity that you need this Tomcat extension, you probably need to be looking at your overall hardware/software environment first.
But in any event, you can safely ignore this message, unless you actually did do the build and install for that enhancement (in which case it's an indicator that installation failed!)
