This is a silly question, probably.
Where is the list object? I've never been able to create it in a patch, so I assume it's not an internal. Is it in one of the external libraries? I'm using pd-extended 0.38-4 (the latest) on OSX. I worry that the problem is the object is only for linux, but it seems quite prevalent in patches I've downloaded from various places, so I thought I'd ask.
