[Nix-dev] cannot build nova

[Tim Barbour]

Thank you. I tried prefetching it, but it makes no difference. The result of
prefetching goes in different store location to the one it is looking for.
Perhaps the package has the wrong hash for python-novaclient-2012.1.tar.gz ?
What is the process for updating the package ?
