Technically, yes, but in reality, not really. If someone tried to
enforce the GPL on you, then you'd just have to make your own custom
build using the BSD licensed code.

That's an interesting question. I think that if you write a patch
that uses a Pd library that is covered by the GPL, technically, your
patch is covered by the GPL. If those libs used the LGPL then you
would not. It's a bit of a gray area, but I release all my code
under the GPL, so I haven't really worried about it.

If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an
idea, which an individual may exclusively possess as long as he keeps
it to himself; but the moment it is divulged, it forces itself into
the possession of everyone, and the receiver cannot dispossess
himself of it. - Thomas Jefferson
