this depends on what exactly you call a "basename". When you have an 
SCons File/Dir Node n, the expression "str(n)" should give you the full 
path of the node, starting at the top-level SConstruct.
This is the key, that SCons uses behind the curtains to identify and 
reference sources and targets within your current build.

If you need the absolute path in your OS-specific filesystem for some 
reason, there is the "abspath" attribute.
You can access it either directly, or reference it within an Action 
command string like this:

     a = SCons.Action.Action("my_parse ${TARGET.abspath} $SOURCE")

Check out the MAN page for the complete list of node path/file 
attributes, that can be used similar to the example above.

Best regards,

Dirk
