That just means you have the 32-bit kernel; 64-bit executables still work
on most Intel-based Macs even with a 32-bit kernel (the exceptions being
early Core 1-based machines), and only machines made within the past year
or so boot to a 64-bit kernel by default.

I believe it was mentioned to you in #haskell that it is an incomplete LLVM
distribution, and you need to install a full LLVM distribution for -fllvm
to work properly.  IIRC you also need to avoid the just-released LLVM 3
(this may also be part of the problem with Xcode 4.2, which is actually a
partial LLVM 3 prerelease).
