When installing package haskell-src-exts via cabal install, I get the error

Language/Haskell/Exts/Syntax.hs:102:7:
    Could not find module `Data.Data':
      it is a member of package base, which is hidden


However, when manually installing

runhaskell Setup.hs configure/build/install

It works fine
Somehow package base is not available in cabal.. don't know why.
