[Haskell-cafe] Need help: Cabal rejecting stringsearch, conflict in base

[Schell Scivally]

It looks like you're using ghc7.7 (soon 7.8) since you're on base-4.7. A
lot of packages just aren't ready for ghc7.7. Either they need bumps to
their dependencies or they need Typeable updates or...or...

If you want to live in the future I'd suggest following the packages in
question to their git repos, cloning them and using those (and possibly
patching them). I've been doing as much of this as I can and it's been
working!

Though I may be misunderstanding your problem and in that case - ignore me!
:)
