Cliff,

The MD5 sum checks happen with downloaded packages too, but computing the
sums themselves is piggybacked on the download process.  When the packages
are local, the sums have to be computed explicitly.

Yes, I see the problem.  Both of these are in my code, so I'll take a look
within a week.

True.  We probably need a command-line option to allow running postinstall
scripts in console windows instead of redirecting them into the log.

Works for me...
