Fails on both Python 2.4 and 2.6 with either ".lib" or "..lib".

### code
#!/usr/bin/env python

from ..lib import mymodule
####

In python/ddl, referencing ../lib/mymodule.py

 ./import_test.py
Traceback (most recent call last):
  File "./import_test.py", line 3, in <module>
    from .lib import mymodule
ValueError: Attempted relative import in non-package


 ls ../lib
mymodule.py
