Hi Roman,

Good point about the permissions, i'll check that.

I don't need to know where I installed pd-extended from (I'm too young to
suffer from dementia). I said it's there in the Ubuntu repos because this
is where I got it (not from puredata.info or anywhere else, and certainly
not from a manually downloaded archive).

Cheers,

Pierre.
