[haskell-llvm] problem installing llvm with cabal

[Nathan Howell]

You should be able to install the llvm 2.9 bits on your Mac and rebuild..
The package installer should do a version check but doesn't, hence the
problem. I don't intend to learn much about autoconf so I'll leave a patch
up to someone else :-)
