    The requirements for anything installable are as follows:

     - we must be able to determine the requirement name
       (or we can't correctly handle the non-upgrade case).

     - for packages with setup requirements, we must also be able
       to determine their requirements without installing additional
       packages (for the same reason as run-time dependencies)

     - we must be able to create a Distribution object exposing the
       above metadata.
