Arduino on Linux

I am trying to get the Arduino board installed on my Fedora Core 5 laptop: no luck yet.
My problem appears to be with the Java GUI

I have followed the guid of an earlier post in this thread, taken form here: http://riereta.net/tiki/tiki-index.php?page=PdInstallationArduino

I was getting a strange error...
check_group_uucp(): error testing lock file creation Error details: Permission deniedcheck_lock_status: No permission to create lock file.
So I copied the proper rxtx version serial lib into the work directory ( cp /usr/java/jre1.5.0_07/lib/i386/librxtxSerial.so work/ )
Now I don't get that error.

When I run arduino:

  1. I get the file selector dialog but no files are displayed.
  2. When I enter a filename a directory within the work directory is created: for example if I try to open Pd_firmware.pde a directory is created work/NullPd_firmware.pde/

Is there a way to upload this firmware to the arduino from the command line?
