Please help.

Answer 1

Finally, I've done it this way:

• uninstalled entire platform with sudo /Library/Haskell/bin/uninstall-hs (https://stackoverflow.com/a/6996284/1749901)
• then following this tutorial first installed apple-gcc42 via brew install apple-gcc42
• then linked it brew link apple-gcc42
• installed platform via brew install haskell-platform
• cabal update
• cabal install cabal-install
• added to PATH $HOME/.cabal/bin (instead of $HOME/Library/Haskell/bin in case of when platform installed via PKG installer from here, obviously because brew makes a little bit different configurations).
• source ~/.bash_profile, then relaunch terminal, so which cabal points to <HOME>/.cabal/bin/cabal, and cabal --version shows 1.18 (not 1.16).
• cabal install happy. At this point I've relaunched terminal one more time, because which happy pointed to local updated (1.19.2) version, but happy --version showed 1.16.x.
• cabal install type-eq -- SUCCEEDED first time!

• finally, cabal install fay fay-base -- SUCCEEDED!

  Installed fay-0.18.1.3
  Installed fay-base-0.18.0.0
  

Phew! Thank you all!

This is a known preprocessor issue on Mavericks. Look here for the solution.

The reasons why this looks like a preprocessor issue are:

1. The line mentioned in the error message contains a CPP macro
2. There's a known issue with CPP on Mavericks
3. The package compiles fine with GHC 7.6.3 (which looks like the version you're using, too) here on Linux

Answer 3

All you need to do is add the cabal install directory to you path! Just add this to your .bash_profile:export PATH="$HOME/Library/Haskell/bin:$PATH"

export PATH="$HOME/Library/Haskell/bin:$PATH"

I was about to uninstall the entire platform, but then I found this to work on Mavericks.
