modify dependencies in local pkgng database

Hi,
recently I installed a new desktop using FreeBSD-10.1-RELEASE image.

After adding some (>1000) packages from default pkg repository, I was
able to start working with kde4, libreoffice, firefox ...

I then tried to switch the gs port (print/ghostscript9) to the more
recent agpl-gs (print/ghostscript9-agpl), both packages are available
in the standard repository:

$ pkg install print/ghostscript9-agpl

This command first suggested to remove all ghostscript dependent stuff
(more than 50 packages , including most of kde4) before installing the
new ghostscript port.

Letting pkg do its job would not help. Reinstalling www/kde4 would
first replace the new ghostscript version with the former one.

So, at last everything would be like before.

Is there a recommended procedure to solve this problem?

$ pkg set -a -o print/ghostscript9:print/ghostscript9-agpl

before trying to install print/ghostscript9-agpl did not help.

Another example would be switching database server from mysql to mariadb.

For now, I'm only able to modify /etc/make.conf, rebuild *all* related
packages, create an additional local package repository from these and
tell pkg to prefer installing packages from there.
