cannot install base-4.3.1.0 package
Hi, how can I install the base-4.3.1.0 package. I tried first
cabal install base
that gives me this error: Resolving dependencies... cabal: Distribution/Client/Dependency/TopDown.hs:169:37-73: Non-exhaustive patterns in lambda I googled for this error and found nothing but the simple statement in the track system http://hackage.haskell.org/trac/hackage/ticket/605: "cabal install base is not expected to work, however the error message should be better, see #597. " (but the link to #547 doesn't solve the problem either) So I downloaded base-4.3.1.0 package from hackage and run:
runhaskell Setup configure
which gives this error: Setup.hs:1:0: attempting to use module `Prelude' (./Prelude.hs) which is not loaded Then I noticed that there is configure script in the base-4.3.1.0 dir, so executed this which yields this error message: config.status: error: cannot find input file: `base.buildinfo.in' Why is it so complicated to install the base package? Thanks for any help!

No. That can't work (at least with GHC). The base package is one of the packages that the compiler was built with, it is impossible to replace it and have a working compiler (again, GHC, for other compilers it might be possible, but I don't think it currently is for any). If you want a compiler with bae-4.3.1.0, install a compiler that was built with it (ghc-7.0.*). Other packages you cannot replace are process, directory, array, containers, integer-(gmp|simple), ghc, ghc-prim, ..., basically everything that comes with a vanilla ghc install (except Cabal, you can install a different version of Cabal without breaking things, afaik).
