I think I was not understanding your problem, nor how portmanager works. 
  Sorry about that.

In general, I do really like how the present "actual-package-depends" 
works, and so I would rather see this kept, and portmanager modified to 
accomodate, rather than the other way around.

Robert sent me some private emails about how "actual-package-depends" 
was messing up portmanager.  Probably he should send the problem 
descriptions to the mailing lists, and maybe someone else could solve 
them.  I thought I had some ideas for quick fixes, but it seems I was 
looking before I was leaping.  I don't really have enough time right now 
for long fixes, so someone else will have to figure it out.  I have to 
say that I simply don't use portmanager or portsinstall or anything like 
that, so I don't know how they work.  (Rather I use my own home brew 
tools for doing the same thing, and since they are home brew and only 
for my use, they don't need to get everything right everytime, they can 
be simple, and they don't have to be at all user-friendly.)
