Freebsd install script: postfix aliases not being setup completely

Just did clean install, update system and run script. Get this error on console every minute or so:

postfix/smtpd: fatal: Open database /aliases.db : no such file or directory

In Webmin in postfix module / Mail aliases I get the followig error:

Failed to query Postfix config command to get the current value of parameter *)^%$#&))( <- garbage value in error code.

If I create an entry in module for aliases database build by newaliases command, and then add an alias to the system, it creates /etc/aliases.db and the console error message stops.

The fail to query message still appears in mail aliases part or postfix module.
