I had rpm-4.0.3-0.55 installed on my machine.  I "upgraded" to
rpm-4.0.3-0.60.  Simple queries like "rpm -q -i" and "rpm -q --scripts"
stopped working.  Furthermore, when I attempted to use "rpm -U --force" to
reinstall the old rpm and rpm-build packages, it complained that only one
major mode could be specified at a time.

I finally had to (a) use rpm2cpio and cpio --extract to put back the files
from the old version of rpm, (b) remove /etc/rpm/macros.db1, (c) restore my
rpm database from a backup, and (d) rerun rpm -U on the packages I had
installed along with rpm-4.0.3-0.60 to bring the database up-to-date.

There is something wrong here.
