[Haskell-cafe] llvm- installation on Mac

I'm trying to get LLVM 3.0 installed and then have the llvm- package install and bind against it with cabal.

I'm on a recent 64 bit Mac which shows up in various messages like: "Target platform inferred as: x86_64-apple-darwin"

I was advised on the Haskell IRC channel to install a 3.0 LLVM from a location like MacPorts first, then point cabal at the location where LLVM was installed with the appropriate config option.
So, I did a "sudo ./port install llvm-3.0", and everything seemed to proceed fine.

Then I did:
cabal install llvm --configure-option=--with-llvm-prefix=/opt/local/libexec/llvm-3.0

This looks promising (compared to missing the config option), but eventually this happens:

Building llvm-base-

I have no idea where "/Users/ian/..." is coming from!

My cabal-fu is extremely weak, so I'll plug on and see if I can figure out how cabal's analysis/build might be going wrong here.
I'd be very grateful for any clues though!
