I had a very similar issue with Ghost4j, i.e.

InvocationTargetException: Unable to load library 'gs': Native library (darwin/libgs.dylib) not found in resource path

Instead of modifying jar files, point jna to the appropriate lib path by setting jna.library.path. In Eclipse, you need to set the system property in run configurations - SO answer for this here - https://stackoverflow.com/a/862405/2163229

If you're using Maven exec:

mvn -Djna.library.path=/opt/local/lib/ exec:java -Dexec.mainClass="foo.bar.NativeThingy"

or

export MAVEN_OPTS="-Djna.library.path=/opt/local/lib/" && mvn exec:java -Dexec.mainClass="foo.bar.NativeThingy"

Obviously, set the path to wherever your libs are installed. In my case, I ran $ locate libgs.dylib and found the above path.
