`cblrepo` gives fairly good messages on unsatisfiable dependencies. Can you post the message you get from it?
Actually, I'm not getting any errors from it, although I can only find the haskell-ghc-paths package in the AUR (I have [haskell] in my pacman.conf), which doesn't seem right to me. I tried looking in the extra/ghc pkgbuild, where I found the following comment, but nothing else: # Special note for devs looking to upgrade this package: # ghc places a unique hash for each library when it is built. # Libraries depend on versions specified by those hashes. # This implies that all libraries need to be rebuilt when ghc is rebuilt. # Also, due to dependency loop problems, haskell-ghc-paths and haddock # do not carry version dependencies. You will have to remember to build them too. Alessandro -- If God had intended for email to be written in HTML, then the traditional signoff of prayers would be </amen> -- Tom Liston
