[Haskell-cafe] openal & alut troubles

The link to the OpenAL documentation [ http://haskell.org/ghc/docs/latest/html/libraries/OpenAL/Sound-OpenAL.html ] from here [ http://www.haskell.org/haskellwiki/OpenAL ] seems to be down. Also, I tried to use cabal to install ALUT and got the following checking for unistd.h... yes checking AL/alut.h usability... no checking AL/alut.h presence... no checking for AL/alut.h... no checking OpenAL/alut.h usability... no checking OpenAL/alut.h presence... no checking for OpenAL/alut.h... no configure: error: no ALUT header found, so this package cannot be built See `config.log' for more details. cabal: Error: some packages failed to install: ALUT-2.1.0.0 failed during the configure step. The exception was: exit: ExitFailure 1 :/
