you are calling SCons with the explicit target "main", so the Default() 
targets don't get selected. Please also check section 10.3 "Command-Line 
Targets" in the UserGuide.
If you remove the funny "sys.argv" guard in your top-level SConstruct 
and call "scons" without any additional arguments, the Install builder 
works as expected.

Because you're using the VariantDir option with duplicate=0, SCons 
includes the variant dirs as well as the source folders. The actual 
library file could exist in either one of them, or both.
