py27-django failed to runserver

[Yoshiaki Miura <miru%explop.com@localhost>]

Hello.

This is first time I post to this list.
I installed py27-django-1.4.1 from pkgsrc-current on my laptop.
When I run 'python2.7 manage.py runserver', I got following errors.

---------------------------------

I ran python2.7 and import gzip manually then I see no errors.

Does anyone have any idea?

Thanks.
