I'm not aware of any specific docs for building 64-bit on os x, but I didn't
have any difficulty last time I tried. The key point is you need a 64-bit
bootstrap compiler (probably until
http://hackage.haskell.org/trac/ghc/ticket/3472 is fixed), however there are
binary distributions of ghc you can use for this. After you install a
64-bit binary, go to the ghc src and do
./configure --with-ghc=/path/to/ghc64bin/ && make
and it should work.
N.B. don't install 32-bit and 64-bit versions of the same ghc, because the
libraries will clobber each other. If you want to have this, change the
version before you install the second arch.
