[sc-users] [linux] swingOSC ERROR: Message 'isMetaClass' notunderstood.

[Angelo Romito]

ou, I just read the SwingOSC/SuperCollider/readme.html on my system, so 
for linux systems you have to copy the content of SCClassLibrary folder 
into /usr/share/SuperCollider/Extensions.... and not into SC/SCClassLib...

but this does unfortunately not effecting my problem... same error
