yum is yuck (errors)

[Ryan D'Baisse]

Okay, I've tried blowing away everything in the /var/yum/cache
directory... done a search... can't find anything nor can I fix this. 
However, when I try to do anything with yum, I get the error below:

[root at localhost yum]# yum clean
rpmdb: PANIC: fatal region error detected; run recovery
error: db4 error(-30978) from dbenv->open: DB_RUNRECOVERY: Fatal
error, run database recovery
error: cannot open Packages index using db3 -  (-30978)
error: cannot open Packages database in /var/lib/rpm
Traceback (most recent call last):

  File "/usr/share/yum/yummain.py", line 163, in main
    (log, errorlog, filelog, conf, cmds) = parseCmdArgs(args)
  File "/usr/share/yum/yummain.py", line 75, in parseCmdArgs

  File "/usr/share/yum/config.py", line 285, in _getsysver
    idx = ts.dbMatch('provides', self.distroverpkg)
TypeError: rpmdb open failed
[root at localhost yum]#


Any ideas?

Thanx,
Ryan
