Rawhide updated breaks yum

[Richard W.M. Jones]

Somehow it's possible to update rpm but not yum and break Rawhide,
using just 'yum' commands, not rpm directly and no forced installs.
Anyway my machine now says:

$ sudo yum install yum
error: db5 error(-30969) from dbenv->open: BDB0091 DB_VERSION_MISMATCH: Database environment version mismatch
error: cannot open Packages index using db5 -  (-30969)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed

'rpm -qa' is fine.

I hope I'll be able to rpm -U the appropriate yum or rpmlib or
whatever to fix this, but be warned ...

Rich.
