ADDING MAC OS X SUPPORT
		The default implementation of stdbuf works on LINUX systems by using
		the $LD_PRELOAD environment variable.  MAC OS X uses a $DYLD_INSERT_LIBRARIES
		environment variable instead.
		
		Add the following to coreutils-8.21/src/stdbuf.c line 236 in the set_LD_PRELOAD function: 
			/* MAC OS X SUPPORT */
			char *DYLD_INSERT_LIBRARIES;
			asprintf (&DYLD_INSERT_LIBRARIES, "DYLD_INSERT_LIBRARIES=%s", libstdbuf);
			putenv (DYLD_INSERT_LIBRARIES);	


BUILDING ON MAC OS X
		NOTE: The coreutils build needs to be modified.  Otherwise, the stdbuf binary
		will not be built.
	
		cd coreutils-8.21
		vi configure   [NOTE: edit line 62775, change "no" to "yes"]
		./configure
		make
