It helps though even in cases where its not png, but perhaps
kdelibs.  Plus we still have a couple of issues.  One is that
the order you install packages will give you a different set
of dependencies.  For example installing perl-5.6.1 first or
installing perl-5.8 first.

I'll try to find some time to think through this, but no guarantees.
