 It looks like `port upgrade outdated` replaced `py34-botocore` with
 `py35-botocore`, making `py34-botocore` inactive, but it can't be
 uninstalled because `py34-s3transfer` depends on it.

 Why is is possible for a port that can't be uninstalled to be made
 inactive?  If the replacement doesn't satisfy the dependency, the original
 should not be made inactive.  If it does satisfy the dependency, the
 original should be uninstallable.
