The hash is used as a way to check for any API changes. It doesn't have to
be cryptographically strong, it just needs to scatter the hashed values
effectively and we could probably use something simpler. I tend to regard
this problem as a Python bug because the standard python modules should be
available on all platforms. In any case, we should find a fix. Please open a
ticket.
