[twill] deprecation warnings in python 2.6

[bruce]

I'm getting these warnings now from twill:

    /usr/lib64/python2.6/site-packages/twill/other_packages/_mechanize_dist/_auth.py:14: DeprecationWarning: the md5 module is deprecated; use hashlib instead
      import re, base64, urlparse, posixpath, md5, sha, sys, copy
    /usr/lib64/python2.6/site-packages/twill/other_packages/_mechanize_dist/_auth.py:14: DeprecationWarning: the sha module is deprecated; use the hashlib module instead

Is there a resolution for this?

Thanks,
-Bruce
