Yeah, portage is a bit odd in telling what is broken. We need a new feature for package manager to handle upgrades nicer (bug #449094) Does this like makes things better for you? emerge -1 =ghc-7.6.2 `haskell-updater -l -q --all`
Running sometimes 'haskel-updater', 'emerge --sync && emerge -uvDN world' and 'revdep-rebuild' the issue disappeared magically.
