What version of the product are you using? On what operating system?

SimpleOpenNI version 0.27
Processing 2.0b7
OSX 10.7.5
  - java version "1.6.0_37"
  - Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
  - Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

Please provide any additional information below.

I've verified many, many times that I have the OpenNI libs installed properly 
and that the Processing library is in the right place.  I've also tried this by 
adding the library to an Eclipse project according to the instructions.  I get 
the same result in both cases.

After some investigation, it appears that according to Oracle, in the 
System.load() method the filename argument must be a complete path name. 
http://docs.oracle.com/javase/6/docs/api/java/lang/System.html#load(java.lang.St
ring) But in 
http://simple-openni.googlecode.com/svn/trunk/SimpleOpenNI-2.0/src/p5_src/Simple
OpenNI.java it appears no path is set for OSX (but is set for Linux and Windows 
for some reason).  (It is an empty string.)  The offending line is 81.
