How to start Sikuli on Linux?

Hi
I have been using Sikuli on windows and love it. Now I am trying to get it to run in linux Lubunto 14

Based on my searching, here are the steps I have followed so far on a fresh install of Lubunto

I did the following with success
sudo apt-get update
sudo apt-get install default-jre
sudo apt-get install sikuli-ide
sudo apt-get install libopencv-dev
sudo apt-get install tesseract-ocr

Then I have tried all of the following without success
sikuli -ide
sikuli -runsetup
sikuli -help

I get this error each time
Can't run this sikuli script: (ide or runsetup or help)
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
     at java.lang.String.substring(String.Java:1967)
     at org.sikuli.script.ScriptRunner.getPyFrom(ScriptRunner.java:109)
     at org.sikuli.script.ScriptRunner.runPython(ScriptRunner.java:103)
     at org.sikuli.script.ScriptRunner.SikuliScript.main(SikuliScript.java:111)

Any idea what I have done wrong?
