$ ls -l /usr/X11R6/bin/freetype-config
-rwxr-xr-x   1 root  wheel  1736 Mar 21  2005 /usr/X11R6/bin/freetype-

I would not expect Apple to update this until the next non-free Mac  
OS X update around the beginning of 2007.

I do plan to build with my own freetype eventually.

$ /usr/X11R6/bin/freetype-config --libs
-L/usr/X11R6/lib -lfreetype

So as you said earlier maybe zlib is built into this version of  
freetype.
