ffmpeg update failed

[Bengt Ahlgren]

I ran into trouble updating ffmpeg according to the recent UPDATING
entry:

portmaster -o multimedia/ffmpeg multimedia/ffmpeg1

after multimedia/ffmpeg was updated, portmaster failed to update
dependencies:

===>>> Updating dependency entry for ffmpeg-2.1,1 in each dependent port
pkg: sqlite: columns package_id, origin are not unique (pkgdb.c:3605)

On a build machine I am using portmaster to update, then build packages
with pkg create -a, and finally a repo with pkg repo.

I discovered this issue after the fact when pkg on a pkg-updated machine
complained that ffmpeg1 was missing, since portmaster already had
removed ffmpeg1.  I have re-installed ffmpeg1 to temporarily fix the
issue, but how can I get rid of the ffmpeg1 dependency?  Do I need to
reinstall everything that has that dependency?  Or is the pkg database
broken beyond repair?
