Tried the manual install instructions found at: 
http://wiki.squeak.org:8080/squeak/6005

and I'm getting almost the same error. I closed all windows, opened the 
Monticello browser and followed the instructions and this appeared:

***System error handling failed***
Original error: MessageNotUnderstood: PluggableButtonMorphPlus>>gradientLook
     Debugger error: MessageNotUnderstood: PluggableSystemWindow>>createBox
etc

The only difference is the original error using the Universe installer 
is: Original error: Error: cannot install color.
