[Media_api] Shared Libraries sous Linux

[Roger Dannenberg]

For use with common music, look at the pm_cl (for Common Lisp) directory 
in the PortMidi distribution. I've been working with Rick Taube and 
Leigh Smith on this. I don't think things are completely settled as 
things do change on both ends and it's tough to keep everything  working 
together, but I think this will get you pretty close. Let me know if you 
get stuck or have corrections to contribute. -Roger
