i guess the problem is that the SC version from the package manager  
is somewhat outdated. Can you check if the class GUI exists  
(SCClassLibrary/Common/GUI/GUI.sc)?

you might be able to get it to work with an older SwingOSC version,  
e.g. v0.513 doesn't yet depend GUI.sc (which might be a problem),  
v0.44 should be working with an older SC version...

ciao, -sciss-
