Haddock fails to cooperate with OS X clang CPP: {{{ <no location info>: module ‘pkgid-pkgversion:Main’ is defined in multiple files: dist/build/tmp-#####/Stuff }}}
A workaround is to pass `--ghc-options=-optP-P` to `cabal haddock`.
This prevents `cabal-install` from being boostrapped, unless `--no-doc` is specified.
The original Haddock ticket and the corresponding Cabal issue were both closed as invalid, but there appears to be no GHC ticket to track the underlying cause. http://trac.haskell.org/haddock/ticket/284 https://github.com/haskell/cabal/issues/1740
