I'm trying to install c2hs with cabal install c2hs.
I created ~/.cabal/bin to install the binary beforehand.
With the command cabal install c2hs to get the errors.

cabal: Error: some packages failed to install:
c2hs-0.16.5 failed during the building phase. The exception was:
ExitFailure 1
What is wrong with the installation? The ghc version is 7.6.3.
The issue was that I installed two different versions of ghc on my mac: one from brew install ghc and the other from haskell platform.
I had to install the newest version of haskell platform, but before doing that I also needed to uninstall old version uninstall-hs only VERSION and brew unistall ghc.
After reinstalling the newest haskell platform, the compilation works fine.
Other method can be using brew brew install haskell-platform.
