[Haskell-cafe] blas: ghc-6.8.2: unable to load package `blas-0.4'

Patric, I am trying to use your blas package, but I am getting a missing symbol error.

import Data.Matrix.Dense.IO mm::(IOMatrix (Int,Int) Double) <- newListMatrix (1,1) [1.0] Loading package storable-complex-0.1 ... linking ... done. Loading package ieee-0.1 ... linking ... done. Loading package old-locale-1.0.0.0 ... linking ... done. Loading package old-time-1.0.0.0 ... linking ... done. Loading package random-1.0.0.0 ... linking ... done. Loading package QuickCheck-1.1.0.0 ... linking ... done.

any ideas what i am missing? Thanks, Anatoly
