Relative Package Import

[Robert Hancock]

mypackage/
          __init__.py
          push/
                    __init__.py
                     dest.py
         feed/
                   __init__py
                    subject.py

In subject.py I have
     from ..push import dest

But i receive the error:
  Caught exception importing module subject:
    File "/usr/local/python/lib/python2.5/site-packages/pychecker/
checker.py", line 621, in setupMainCode()
      module = imp.load_module(self.moduleName, file, filename, smt)
    File "subject.py", line 1, in <module>()
      from ..feed import dest
  ValueError: Attempted relative import in non-package

What am I missing?
