Comment:

 I cannot reproduce this problem. I just tested GHC 7.4.2 x86_64 (using the
 OS X installer package from GHC HQ) on OS X 10.8 DP4 with Xcode 4.5 DP
 (using the command line tools installed by that version of Xcode). I can
 compile and validate GHC HEAD without any problems.

 Can you please try installing Xcode 4.5 DP and make sure to reinstall the
 command line tools, just to be sure, and give this another try? Thanks.
