Please note that a full move toward scons is not likely to happen soon. 
It will have to be the default build system for both numpy and scipy, 
unless someone hacks a ctypes-based extension builder (e.g dynamically 
loaded library builder) for distutils.

Another issue is the detection of a 3rd party library to be usable by 
ctypes: this should be easy to do in distutils, and not too difficult 
for scons.

cheers,

David
