Can't download source file for Python Quickbooks package

[D'Arcy Cain <darcy%NetBSD.org@localhost>]

I am trying to create a package and I can't seem to figure out the 
MASTER_SITES line.

DISTNAME=      python-quickbooks-0.6.0
PKGNAME=       ${PYPKGPREFIX}-quickbooks-0.6.0
CATEGORIES=    python finance
MASTER_SITES=  https://pypi.python.org/packages/p/python-quickbooks

I have tried different variations but nothing seems to work.  Can 
someone point me at the solution please?  Here is their home page:

https://github.com/sidecars/python-quickbooks

Cheers.
