Azureus requires Java 1.4.x or newer to run.
1. Extract the contents of this .tar.bz2 file.
2. Change to the 'azureus' directory where the files were extracted.
3. Start Azureus by running the script named 'azureus'; ex. "./azureus"
i just did as it said, extract to your preferred directory, then ran the azureus script and works fine.
