[quote]hmmm.... SwingOSC initializes the following classes upon compilation:

NetAddr
SwingOptions	(part of SwingOSC)
OSCresponder
AppClock
JFont			(part of SwingOSC)

one of these seems to be absent... but why?

can you temporarily remove the SwingOSC class folder from /usr/share/ 
SuperCollider/Extensions, and see if SuperCollider starts up without  
errors? if so, can you check if all of the above classes (except  
SwingOptions and JFont) exist? (simply type in the class name and  
execute that).

what SwingOSC version are you using, the lastest? did you build SC  
yourself from source or did you get it with a package manager?

my system is just 20hours old:
-I installed Ubuntu 7.04
-then emacs, supercollider, jack (all with package mangager)
-then I found out, that there exists Ubuntu Studio with many audio software, and installed 2 packages: ubuntustudio-audio and ubuntustudio-audio-plugins
-then I tried to install SwingOSC

Ok, removed the SwingOSC class folder from /usr/share/ 
SuperCollider/Extensions

I get no errors:
