portupgrade failure

[Elliot Finley]

After upgrading to the latest portupgrade:

dns root:~#>portupgrade -v
portupgrade 2.0.1 (2006/06/18)

I got a failure on 2 out of 4 boxes.  Now when I use portversion,
portupgrade, or pkgdb I get:

backup root:/usr/ports#>portversion
[Updating the pkgdb <format:bdb1_btree> in /var/db/pkg ... - 34 packages
found (-0 +0) Command failed [exit code 1]: /usr/local/sbin/pkgdb -aFQ

Any pointers on how to fix this would be appreciated.

Thanks
Elliot
