I had sort of arrived at having to do that anyway to avoid the need for
the dub program on the test server. I think we have to assume the Dub
tool always does exactly what is says it does and so ignore it for all
the tests. If I extract the subprocess call into a separate Python
function, that enables mocking. For testing the basic stuff this should
be OK. I have created a special case of the unit-threaded package
because it needs a special builder for writing suite files. Most of
that is already amenable to unit test, but not end-to-end unless dub is
available.

I will set about putting these tests in place, but given the SCons test
infrastructure a full end-to-end system test may have to be left to
what happens in the field.
