I've been using blas recently with very good results.  It's great if
all you need are simple matrix operations.  I just wanted to point out
that it doesn't install on ghc-6.12.1 because the ieee dependency
provides a type class instance for CLDouble, which was omitted from
ghc-6.12.1.  I got around this by commenting out the instance in
CLDouble in the ieee package, then everything installed and runs
properly (using OSX 10.6, compiled with -faccelerate).
