[Haskell-cafe] Re: Troubles Building LLVM (Fixed)

[Keith Sheppard]

Hello, in case someone else hits this problem I was able to fix it by
installing the latest haskell platform via macports.

- I uninstalled ghc "sudo /Library/Frameworks/GHC.framework/Tools/Uninstaller"
- deleted ~/.ghc and ~/.cabal
- did a "sudo port install haskell-platform" (be prepared for this to
take a couple of hours). ghc --version gives 6.10.4
- cabal install llvm

I still don't know the root cause of the build error but now the llvm
examples build and run with no errors.
