I did install `ossp-uuid' with 5.28, but a new run of `port mpkg'
(without a `port clean', though) gives the same result.

Let me reformulate my question: Does the way how I have installed
MacPorts packages on my computer influence how `port mpkg' works for a
given package?  Given that `port mpkg' rebuilds all packages, I would
expect no.  Instead, I would expect some control file (or a special
command line sequence) to control variants of package dependencies.

Is this flawed thinking?
