Nope - 'fraid not :(

I've updated just 5 minutes ago (10:25am GMT) and running "bmake"
still causes the previous output: The required file isn't fetched, and
then the digest stage aborts because the checksum of the
(non-existant) file does match what is expected.

This appears to happen for all packages.

What files were changed to cause the original breakage?  If I know the
specific files, I can revert them to a couple of days ago and check
that everything again works, and then diff the latest version with the
last to see what might be breaking things...
