OS Glob's are rarely recursive, Glob is modelled after that.
That said a recursive find mechanism would often come in handy.

You don't need to do this, but when dealing with VariantDir's it is much
easier to do it this way.
Otherwise you need to make sure that your logic is requesting the files in
each variant dir properly.
By placing the SConscript in the variantDir, SCons takes care of that for
you.

Can you reproduce this in a simple SConstruct?
Any reason to use sys.stdout.write over print?
