Bug#548479: exim4: please use newer bdb

[Clint Adams]

Package: exim4
Version: 4.69-11
Severity: wishlist
User: pkg-db-devel at lists.alioth.debian.org
Usertags: oldbdb db4.6

At some point, db4.6 will be removed from unstable.

Please change your build dependency to libdb-dev (>= 4.7) or, if you
need a specific version, libdb4.8-dev.

When removal becomes imminent, the severity of this bug, if still
open, will be raised.
