[Wrapper-user] Where do I get the Mac OS X jni libraries?

[Jeremy F. <jer...@ya...>]

I downloaded Archiva 1.3.1 earlier today. (zip version).It appears to be utilising your software and I get the following:
WARNING - Unable to load the Wrapper's native library because none of the
following files:libwrapper-macosx-x86-64.jniliblibwrapper-macosx-universal-64.jniliblibwrapper.jnilib

could be located on the following java.library.path:

/opt/apache-archiva-1.3.1/lib

Please see the documentation for the wrapper.java.library.path
configuration property.
System signals will not be handled correctly.

java -version yields:java version "1.6.0_20"Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-10M3065)Java
HotSpot(TM) 64-Bit Server VM (build 16.3-b01-279, mixed mode)===
Java Preferences in Utilities section:It stipulates : Java Applications,
Web Start applications and command line tools use 'this order' to determine the most appropriate version to use..The panel has the 64 bit version listed above the 32 bit one. So I'd assume 64 bit was being chosen.

===
Searching on the term wrapper.java.library.path yielded a file in the archiva conf folder called wrapper.conf.That has a slew of 20 jars and excludes
the ones the message relates to.Don't know where I'd get these (or why I need them)
===
Can someone enlighten me? ===
Also what's the deal with system signals?Are some sort of event listeners supposed to make use of these?
