I think Joris mentioned scons because that's the easiest way to build a 
shared library in a cross platform way (taking care of -fPIC on unix, 
linker option, etc...).

Scons is like make, and SConstruct files are like makefiles: you just 
call scons instead of make when you have a SConstruct file.

I think this had nothing to do with using scons to build numpy/scipy per 
se (numpy svn does not include scons, BTW, only hooks to call scons from 
distutils).
