I don't know, if this really qualifies as 'better' but it works for me.

I walk the dependency tree 'manually' with a small generator like follows:

def preorder_deptree(node):
    yield node
    for c in node.all_children():
        for n in preorder_deptree(c):
            yield n

Calling something like

for node in preorder_deptree(File('your_header')):
        pass

would get you all dependencies of 'your_header'.


HTH,
