[Pharo-project] Using Open Sound Control with Pharo 1.1.1 one click

Hello I am trying to create some simple controls for an OSX Quartz Composer application. The app supports Open Sound Control - basically UDP multicast commands. I managed to load the OSC package from squeak source using Pharo 1.0. But I couldn't get UDP to work - the system report a Prim Failure. I updated to 1.1.1 and OSC now fails to load, due to a syntax error. Before I dig into this any further, I need to know whether UDP is actually working under Pharo - searching the list archive showed messages saying it was broken, but the bug tracker doesn't show it as a bug. Can anyone enlighten me? Cheers Andy
