OpenIndiana Upgrade from 151a3 to 151a4

On the 4th of May OpenIndiana released a new dev repo with the ReleaseNotes.

My first attempt to upgrade was not successful, because I had a mixture of
So I had on my system imagemagick from and the sfe repo.

I had to cleanup a lot of packages before I could updated. The easiest way
for me was to use the graphical packagemanger, because here I could
select the packages and try to remove them. When the system said that there
are more depending packages I could add them.

But after this I could updated without problems:
