Problem using rxtx

Hi all, I am Lorenzo.
I am a new user of Arduino, I installed Arduino's softrare on my Mac, with OSX Snow Leopard.

Arduino works perfectly, but I have some issues with rxtx libraries.
I downloaded the package, and I copied RXTXcomm.jar and librxtxSerial.jnlib, from the OSX folder to /library/java/extensions.

I started compiling the program SerialTest with javac, and the compilation worked perfectly (no errors)

The problem is that when i run "java SerialTest", the terminal give some errors:

java.lang.UnsatisfiedLinkError: /Library/Java/Extensions/librxtxSerial.jnilib:  no suitable image found.  Did find:  /Library/Java/Extensions/librxtxSerial.jnilib: no matching architecture in universal wrapper thrown while loading gnu.io.RXTXCommDriver
Exception in thread "main" java.lang.UnsatisfiedLinkError: /Library/Java/Extensions/librxtxSerial.jnilib:  no suitable image found.  Did find:  /Library/Java/Extensions/librxtxSerial.jnilib: no matching architecture in universal wrapper

There are three weeks that I'm trying to find out a solution, but never worked fine...
I hope somebody can help me :), Lorenzo

It seems to be no solution :cry:

I don't have a MAC but I thought that for the MAC the RXTX libraries ALSO had an "installer" application to make sure it was in the right "places".
