+- Add 2 new options to ``--with-universal-archs`` on MacOSX: 
+  ``intel`` builds a distribution with ``i386`` and ``x86_64`` architectures,
+  while ``3-way`` builds a distribution with the ``ppc``, ``i386`` 
+  and ``x86_64`` architectures. 
+  
 - Issue #6802: Fix build issues on MacOSX 10.6
 
 - Issue #6244: Allow detect_tkinter to look for Tcl/Tk 8.6.
