ghc6 & ghc6-doc uninstallable together
ghc6 provides and conflicts on haddock
ghc6-doc comes from ghc7, and depends on ghc-doc
ghc-doc depends on haddock-interface-16, which comes from ghc-haddock
ghc-haddock provides and conflicts on haddock
haskell-dlist, haskell-bytestring-show, haskell-cereal,
haskell-directory-tree and haskell-monadcatchio-transformers have
been put to "failed" on armel since they build-depend on ghc6 & ghc6-doc.
if this will be fixed by new uploads of the affected packages, nothing
needs to done from your side.
If ghc6 and ghc6-doc become co-installable again, notify me and I'll remove
the packages from failed.
