I'm not quite sure, since the code in your SConstruct and the project 
tree in your SO question are slightly out of sync. But I'd like to 
suggest, turning the setup of the SConstructs/SConscripts around a bit 
for your case.
I'm assuming that you only need a single "bin" output folder, in which 
case the usage of variant_dir is not necessary.

Try to create simple SConscripts in your "obj" folders and the "bin" 
folder directly, which you include via SConscript() from the top-level 
SConstruct:

   env = Environment()
   Export('env')

   SConscript('object/prog1/SConscript')
   SConscript('object/prog2/SConscript')

   SConscript('bin/SConscript')

The sub-SConscripts then look like:

   Import('env')

   env.SharedObject('program1.os','#src/prog1/program1.cpp')


and:

   Import('env')
   env.Program('program1','#object/prog1/program1.os')


Best regards,
