No, you're not missing anything. :-)

We had actually talked about this feature but not implemented it yet.
This is in the TODO file listed under:

--developer switch - run MTT against a current install

the intent of which was to do pretty much exactly what you described.
The pieces that are missing are that MTT pretty much needs the MPI Get
and Install phases, if for nothing other than installing the Right
meta-data in its data structures so that it "knows" about that OMPI

So we might want to add Get and Install modules that do nothing in terms
of the scratch tree, but end up providing enough meta information that
they can be added to the xml files. These are not "Null" modules,
strictly speaking, because they need to extract name, version,
directory, etc. information (some of which is probably OMPI-specific).

Make sense?
