Arduino 0013 released.

I installed the lib per instructions.
I am getting

Uncaught exception in main method: java.lang.UnsatisfiedLinkError: /Applications/ARDUINO/arduino-0011/Arduino 11.app/Contents/Resources/Java/librxtxSerial.jnilib:

with both 11 and 13. (IMac, Leopard 10.5)

How about some accurate complete information we can use to fix this problem. ANYONE?
