building hmatrix on OSX

Question

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.
