Description:
The package community/python-html5lib has a missing dependency. I installed the package, and when I try to
import html5lib
from python, it says "ImportError: No module name six".
So I consider it should depend on community/python-six.

Additional info:
* package version(s): 0.999-4
* config and/or log files etc.
In [1]: import html5lib
