[Haskell-beginners] Haskell Platform on OS X Lion with Xcode 4.3

Greetings. I have been had the Haskell Platform installed on my Mac for a long time. Last week I got a new faster Mac which is running OS X 10.7.3 and has Xcode 4.3 installed. I cannot install the Haskell Platform on it because the HP complains that it cannot find the developer tools. (BTW, Xcode 4.3 *does* appear to include the 10.5 SDK. Has anyone had luck installing the HP in this environment? (I know that this is not the ideal mailing list for this question. The haskell-platform mailing list seems to be broken at the moment, as is the haskell-platform bug reporting trac website.) - P -
