[Media_api] problem compiling portmidi test programs on Mac OS 10.4

[Roger Dannenberg]

Bill,
	I believe Leigh and I are using GCC 4.0.1, so that might be causing a 
problem. I don't know what's happening, but after Googling for 
libobjc.A.dylib, I found "The libobjc.A.dylib file contains a 
developmental copy of the Objective-C runtime. It’s not necessary for 
normal development." I assume this is getting pulled in by one of the 
frameworks (CoreMIDI, CoreFoundation, or CoreAudio) used by PortMidi 
applications, but I don't know why.
	The pm_mac.xcodeproj should be equivalent to the Makefile.osx except 
for the xcode configuration and installation options, so if Leigh's 
command line works for you, I'll track down the Makefile.osx problem. (I 
do all my testing with Makefile.osx).
