Comment (by robe):

 Replying to [comment:1 strk]:
 > It fails loading 3.5.1 because it was built against a newer version of
 GEOS  which isn't found at loading time. We could make such cases a SKIP
 instead of a FAIL, given the focus is on testing the target (3.4 in this
 case) rather than the source of the downgrade (3.5.1 in this case). Or you
 can pass --skip-tests to fine tune which tests to skip ("downgrade
 3.5.1dev--3.4.5" in this specific case)


 Yah I think this would be the best thing to do cause there is no way
 winnie and debbie could ever do this.  For now I'm just going to skip the
 upgrade tests on debbie so I can move on.
