hmatrix  uses a custom configure script which I think is supposed to
make live easier for Linux users. Unfortunately, it doesn't work on
MacOS X; you have to deactivate it. If I remember correctly, you can do
this with changing the build type to

   build-type: Simple

in the cabal file. Then, add the relevant libraries

   extra-lib-dirs: /opt/local/lib/
   extra-include-dirs: /opt/local/include/
   extra-libraries: gsl
   framework: Accelerate
   -- or  framework: vecLib  for earlier versions of MacOS X

and off you go.
