[Haskell-beginners] Installing hmatrix on OS X

[Duncan Mortimer]

Ooops.  Cancel that --- I didn't get any errors on running "cabal
install", and "hmatrix-0.8.2.0" is listed in my ghc-pkg list.
However, on attempting to run the tests listed on:

http://sites.google.com/site/wwwhmatrix/installation

i.e.:  (in ghci):

> import Numeric.LinearAlgebra.Tests
> runTests 20

I get the error:

...
...
Loading package hmatrix-0.8.2.0 ... linking ... <interactive>:
unknown symbol `_zgemm_'
ghc: unable to load package `hmatrix-0.8.2.0'

Does anyone have any suggestions as to what's going on now?

Thanks,
Duncan
