You need to add the enable-universalsdk parameter to configure:

  ... --enable-universalsdk=/Developer/SDKs/MacOSX10.6.sdk

Be aware, though, that universal build support on 10.6 is a bit of a 
work in progress as there are still some interesting unexplained 
universal build issues when building on Snow Leopard (see, for instance, 
the comments in http://bugs.python.org/issue6957).  At the moment, the 
focus is on getting 2.6.3 out the door and the standard installer for 
that will be built on 10.5.
