Sadly the upgrade suggestion won't work. If you read the other details in https://github.com/pypa/pip/issues/24 you will see why

pip will build all packages first, before attempting to install them. So with a requirements file like the following

numpy==1.7.1
scipy==0.13.2
statsmodels==0.5.0

The build of statsmodels will fail with the following statement

ImportError: statsmodels requires numpy

The workaround given for manually calling pip for each entry in the requirements file (via a shell script) seems to be the only current solution.
