Haven't tried it though.
does running haskell-updater help?
I didn't think to isolate the problem, but emerge -av $(eix --only-names -C dev-haskell) darcs made the errors go away.
Problem always arises when you update one of intermediate libraries used by others. In this case mtl was updated recently (bug #391591) and broke hashed-storage. haskell-updater is a haskellish twin of revdep-rebuild for C library.
Finally made it. Here's how: initial state mtl-1.1.0.2 installed. darcs compiled because of flag update. steps: mtl update to 1.1.1.1 execute haskell-updater program. => along with other packages darcs is successfully rebuilt. Done. Thanks to all of you. N.B. Initially I've tried revdep-rebuild without any parameter which didn't help. I guess Gordon Pettey's way of revdep-rebuild would have made it.
