I can confirm that Mark's Haskell 2011.2.0.0-x86_64 Mac OS X installer fix works :)

cd /Library/Haskell/ghc-7.0.2/lib/registrations
for c in *.conf; do echo == $c ==; ghc-pkg register --force $c; done

My goal is to get Haskell ncurses working. c2hs is required, so I did:

$ cabal --version
cabal-install version 0.10.2
using version 1.10.1.0 of the Cabal library

$ cabal install c2hs
$ c2hs
-bash: c2hs: command not found

It appears Cabal never added ~/Library/Haskell/ghc-7.0.2/lib/c2hs-0.16.3/bin to PATH. It's easy enough for me personally to fix, but Haskell 2010 didn't have this problem.

Well that's no fun! The install looks like it mostly worked, execept that the final registration of the installed packages failed because for some reason the script has them out of order.

You can "fix up" your install by doing this:

cd /Library/Haskell/ghc-7.0.2/lib/registrations
for c in *.conf; do echo == $c ==; ghc-pkg register --force $c; done

I'll have to look into why that build of the package got the files out of order...
