Problems with bacula backport?

[Anthony DeRobertis <aderobertis@metrics.net>]

First, there does not seem to be an amd64 build. So I grabbed the source 
from bpo and did a dpkg-buildpackage. No problems there.

Second, bacula-director-pgsql seems to be missing a dependency of 
dbconfig-common:

# dpkg -i bacula-director-pgsql_1.38.11-0bpo1~asd1_amd64.deb 
(Reading database ... 58748 files and directories currently installed.)
