I tested the 64-bit bindists and compiled the source from scratch on Lion.  It all works.  You are right that the bindists use the default gcc (i.e., the one with the LLVM backend).  That is ok, though, as GHC supplies the stack unwinding linker option.

When compiling the source, the build system picks gcc-4.2 (as it should, otherwise the RTS wouldn't compile).

I still think that the bindists should use gcc-4.2 as well.  However, that's nothing that should hold up the 7.2.1 release.
