for this first version you have to call the SConscript in the 
variant_dir, no matter whether you're using "duplicate=0" or "duplicate=1".
So, the call of SConscript above should look like this:

   env.SConscript(['build/SConscript'])

This is also described in some detail in the MAN page...and the rather 
unusual notation in this case is the reason why most people prefer the 
"variant_dir=" syntax... ;)

Best regards,

Dirk
