I filed a bug report for a compile error in the latest GHC build, but nobody has responded to it for 4 days. I might as well try to fix it myself, but I'm just a functional programming and Haskell beginner.
Here's the bug I filed: http://hackage.haskell.org/trac/ghc/ticket/715
Here's what the output of GHC says:

Unless you need the OpenAL library, you could try configuring with --disable-openal as a workaround. I imagine the OpenAL maintainer will get to this bug in due course.
Hmmm, this is strange: I've built GHC from the "official" darcs repository yesterday without any problems. I'm having a look at what might be the difference when I have all my tools back at the bleeding edge...
I always get this error if I try to build ghc 6.5 on Debian 3.1 without --disable-openal --disable-alut. I guess it has to do with older version of libopenal (it's 0.2004090900-1.1 here).
