Errors in 0.8.1 when run with Django/uWSGI, but not with Django's dev runserver
I'm using pandas in a Django application running on Ubuntu 12.04 and after upgrading from pandas 0.6.1 to 0.8.1 I'm getting some errors that completely prevent the application from running.

If I run Django's development server (manage.py runserver), everything works fine, but if instead I run uWSGI I see the following 2 tracebacks in my uwsgi log:

```
Traceback (most recent call last):

```

After reading in #284, I thought it may be a path issue so I tried overwriting `sys.path` in my uwsgi configuration file so that it's the exact same path that the dev server sets up for me, but that didn't help.

Any tips / debugging ideas / help on the above would be greatly appreciated.

Thank you!
