Haddock 2.x is actually built into ghc, which is why there's such a  
close version dependency on the two.  I haven't checked, but it's  
possible that installing ghc is installing haddock automatically, such  
that ghc knows about it but port doesn't.  (This would be a bug in the  
ghc port.)

Actually, poking about on my system, what I see is:
- haddock-ghc is installed by the ghc port
- /usr/bin/haddock is a symlink into the framework-based ghc install  
from haskell.org/ghc, unrelated to ports

You may want to verify which ghc and haddock you're getting, and  
adjust your path or remove the interfering ghc install.
