Exit Code 11 installing Persistent (Yesod)

Question

I'm trying to install Yesod on my Mac (running Mavericks), but installation fails because of an error installing Persistent. Specifically, cabal install persistent yields:

Failed to install persistent-1.3.0.2
Updating documentation index /Users/Max/Library/Haskell/doc/index.html
cabal: Error: some packages failed to install:
persistent-1.3.0.2 failed during the building phase. The exception was:
ExitFailure 11

(The full output is available as a gist)

I don't think this is an issue with conflicts, because I ran rm -rf ~/.ghc ~/.cabal before trying this (though I think 3 globally installed packages might not have been erased—unsure).

I'm using the latest Haskell Platform with the ghc-clang-wrapper script.

Cabal versions:

$ cabal --version
cabal-install version 1.16.0.2
using version 1.16.0 of the Cabal library

GHC version:

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.6.3

Answer 1

Reinstalling Haskell platform allowed me to install Persistent, but the real issue was that I needed to install gcc48. Installing this cleared everything up. https://stackoverflow.com/a/21285413/1176156
