Also, dory is showing a different failure mode, in which it's not even
getting to the pg_upgrade test:

The regular installcheck test is dying with

Can't locate object method "installcheck_internal" via package "serial" (perhaps you forgot to load "serial"?) at
vcregress.plline 105. 

Seems like some kind of syntax problem in the patch's change to
vcregress.pl?  I'm not enough of a Perl guy to diagnose it.
