I would next run the failing tests one at a time to see why they are failing. Since the test scripts appear to be crashing early (judging by how many tests are being planned versus being run), my guess is that there's another module not installed or misconfigured.

Test them one by one by changing into the installation folder and running:

prove -lrv t\Blat.t
[download]

... etc.

But I do think installing a Bioperl image on a linux VM sounds very sensible.
