I'm trying to build hmatrix-0.16.1.1 on OSX 10.10.1, and I'm running into some undefined C functions and types in src/C/vector-aux.c:

- struct random_data

- random_r()

- initstate_r()

A specific error:

src/C/vector-aux.c:738:24:

error: variable has incomplete type 'struct random_data'

struct random_data buffer;

On a Linux system they seem to be defined in stdlib.h, but that doesn't seem to be the case on OSX.

Is there a way to work around this?

FWIW, I'm using GHC for OSX (https://ghcformacosx.github.io/) and I've installed `gsl` via `brew install gsl`.
