instead of fiddling with Node objects yourself, you could also simly call:

   scons --tree=all executable_name

which would print you the list of sources and dependencies for the single target "executable_name". Is this perhaps what you're 
actually after?
Note how wrapping a File/Dir object in the "str()" method as in

   f = env.File('local.file')
   print str(f)

will yield the relative path of the Node object...

Best regards,
