I am not having good luck with this.
I have followed the instructions but I'm not getting what I think I should be.
When I start up arduino from the command line I get the following screen:

And when I click on any file to open it I get the following:
java.lang.ClassNotFoundException: com.sun.java.swing.plaf.gtk.GTKLookAndFeel not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:lib/,file:lib/build/,file:lib/pde.jar,file:lib/antlr.jar,file:lib/oro.jar,file:lib/registry.jar,file:lib/mrj.jar,file:lib/RXTXcomm.jar], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7
./arduino: line 16: 24806 Segmentation fault java processing.app.Base
I know I'm missing something, but I don't know what it is.
Can some one throw me a line here?
Thanks
