Can't install django-openid-auth 0.4 via pip

Pip tells me that the latest version is 0.4, but when I do a "pip install django-openid-auth==0.4", it can't find the version. (http://paste.ubuntu.com/732749/)

Also see pip logs here http://paste.ubuntu.com/732755/

I suspect the reason for this is the filename in PyPI being django-openid-auth_0.4.tar.gz instead of django-openid-auth-0.4.tar.gz. I checked older releases and it has always been hyphen before the version number.
