[Haskell-cafe] hmatrix on os x

hello -- i've been having a heck of a time installing hmatrix on mac os x. i've seen the help pages including http://mit.edu/harold/Public/easyVisionNotes.html but they haven't helped me. my setup is haskell platform 2009.2.0.2 (ghc 6.10.4) os x 10.5 macports -- i've tried installing gsl and gsl-devel to no avail. i've tried cabal install with various options, to no avail. has anyone else have luck with this? best, ben
