>>>>> STAGE 1 of 4: Cleaning the package database.

The nautilus-media port was removed, because its functionality
was merged into another application. This next step might complain
about the nautilus-media port no longer existing. When it asks what
you want to do about it, you can either choose choose "[no]" to
ignore the issue, or, if (and only if!) you are very familiar with
pkgdb(1), you can hit CTRL-D to remove the dependency.

===> Running /usr/local/sbin/pkgdb to start with a consistent package

FAILED.
ERROR: /usr/local/sbin/pkgdb repair has failed. Please repair the package
database by hand (run "pkgdb -F"), then re-run this script. If you require
additional help, compress /var/tmp/gnome_upgrade_log.8OrDJM, and send it to
freebsd-gnome at FreeBSD.org.

and run pkgdb -F:lp# pkgdb -F
