I don't get it. I'm using the latest Pd version but since some time the vbap extension doesn't work anymore. Even when I open the demo patches, its got a dashed red line arround it. When I message "define_loudspeakers ..." (still in the help patch) it returns
error: vbap: no method for 'define_loudspeakers'

What did I do wrong? I even reinstalled Pd to make sure I didn't fuck things up even though I didn't mess with properties and libraries except audio of course ...
