ghostscript9 installed; OK for ghostscript8 dependency?

[Mike Brown]

I had ghostscript8 installed, but after an ordinary upgrade (I think, I mean, 
I don't recall doing anything unusual), I ended up with ghostscript9. After 
that, portmaster complained that ghostscript8 was a dependency for a couple of 
the other installed ports:

$ portmaster --check-depends
[...]
===>>> Checking mediawiki-1.16.1
        ===>>> print/ghostscript8-nox11 is listed as a dependency
        ===>>> but there is no installed version

The same dependency is listed for pecl-imagick.

I went ahead and answered 'y' to the question of whether to delete the 
dependency, but now I'm wondering if that was the wrong thing to do.
Was it?
