GHC 7.0.3 solve the compatibility problems between Xcode 4 and GHC.
No news about a future release of Haskell Platform. Sorry.

I've been using the Haskell package for the last week to learn Haskell, but I've found several issues that make it feel like abandonware (which I know its not).
I'm running OS X 10.6.7 with XCode 4 and installed the Haskell Platform 2011.2.0.0-x86_64.pkg. (I just realized this is labeled an experiment build. I hope that isn't the root of my problems. Tell me if it is.)
ghci and runhaskell all work fine, which has been enough to get me into the language (which I'm quite enjoying).
ghc will not compile the simplest program without manually specifying -L/usr/lib:
$ cat hello_world.hs main = putStrLn "hello, world"
$ ghc --make hello_world Linking hello_world ... ld: library not found for -lcrt1.10.5.o collect2: ld returned 1 exit status
$ ghc -L/usr/lib --make hello_world Linking hello_world ... ld: warning: -read_only_relocs cannot be used with x86_64 ld: warning: could not create compact unwind for _ffi_call_unix64: does not use RBP or RSP based frame
Seems like a pretty important directory to include, making it feel like a very serious oversight. I've been told this is because the Haskell Package is linked to the /Developer/SDKs/MacOSX10.5.sdk/ directory, even though the package is explicitly labeled for 10.6.
This error comes up in Cabal installs as well. In fact, I have not been able to get a singe Cabal install to succeed out-of-the-box. I've tried a variety of packages such as vec, pandoc, yi.
I'm understandably hesitant to just symlink my entire 10.6 SDK as 10.5 just to get this to work. I would greatly appreciate alternative solutions.
