[OpenIndiana-discuss] Package perl-584 needs updating, but can't be updated (as seen from the package manager or pkg -u).

[Hans J. Albertsson]

In the aftermath of my file system adventures when updating to 151a4, I 
now have one mysterious "problem" left.

Well, it's not really a problem, just confusing and a little bit 
mysterious to me, since I don't really know the IPS stuff that well.

Thing is I got to the point, doing lots of "pfexec pkg -R /otherBE fix 
packagename", where my system reported no serious problems in pkg fix, and
the package manager had a clean and consistent, and probably complete 
view to present.

Then suddenly a bunch of python-related packages were updatable, and I 
let updatemanager do that.

It set up a new BE, and after booting over to that one, I ran Package 
Manager. I clicked around a bit, and finally selected All publishers, 
All packages and View Updates.

Then there was one update: perl-584.

Now this guy cannot be updated, it cannot be removed, and it is actually 
EMPTY and just has a marker saying it has been renamed to perl-510.

It's no problem, really, but:

What determines if a package is reported as updatable??

pkg -u shows this same package as updatable, so it's not just the GUI 
application that's wrong, here.
