rpm dep ordering, specifically OpenOffice

[Jerry Amundson <jamundso gmail com>]

On a whim, I removed openoffice* from my laptop running rawhide.
I saw two errors regarding unopkg because openoffice-core was removed
before the two packages whose %postun tried to call unopkg.
1. Specifically with OO, does it matter? Is there cruft left because
some cleanup is not done?
2. In general, can anything be done? I thought this was discussed
recently, but can't recall the outcome.
Thanks,
jerry
