[Haskell-cafe] Cabal problem, broken packages?

[Volker Wysk]

Hi!

I've lately set up the Haskell environment on my Linux box, with no
problems. Then I have installed some packages with "cabal install", again
without problems. But now I'm trying to install another package and I get a
dependency conflict. It doesn't seem to matter which package I try to
install:


desktop ~ $ cabal install rfc5051
Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] next goal: directory (user goal)
[__0] rejecting: directory-1.3.8.0 (constraint from user target requires

user

(constraint from user target requires ==8.8.4)
[__1] fail (backjumping, conflict set: directory, ghc)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: directory, ghc


This doesn't make much sense to me. How can I repair it? Are the packages
broken? Can a solution somehow be specified?

Cheers,
Volker
