Why is it choosing [email protected] here? I see two places where we went wrong.
First of all, py-configparser doesn't depend on py-ordereddict unless we are building with Python 2.6. Spack should still default to the latest version of Python 2.7.
Second, the following doesn't fare any better:
$ spack spec py-ordereddict

This is also choosing [email protected] even though it should be choosing the latest version of Python 2.6 in Spack.
