So do you reckon PortMIDI is creating some global
variables etc that might linger in the process even after
the library module it sits in gets unloaded?

There can be many reasons of this problem. It is possible that
the libraries do not actually get unloaded on OS X, or the error
is related to how PortMidi uses the API of the system. As I do
not have access to a Mac, nor am I familiar with that platform,
I can only guess.
