Relative module import name conflict

[optiz0r]

I'd love to be able to use this module, but I have an unresolvable name conflict with an existing dns module. ciscoconfparse uses relative imports, and since my app is higher on the PYTHONPATH this means my dns module is being loaded in preference to the ciscoconfparse internal one.

>>> print "\n".join(sys.path)

>>> from ciscoconfparse import CiscoConfParse

    from dns.exception import DNSException
ImportError: No module named exception

If ciscoconfparse used absolute imports instead, I think this problem could be avoided. Short of renaming the local module in my application (not simple), I don't think there's any way I can work around it without code changes in ciscoconfparse.

You should use ciscoconfparse in a virtualenv that has the correct dns module.

FTR I ended up refactoring my own codebase so that instead of having a top-level package named dns I had prefix.dns.
