Odd stuff, in the latest gsl from the science overlay someone decided not to support linking with an external cblas anymore. For some reasons it breaks gsl on OS X. I have no idea if it is also broken in the main tree if you use internal gslcblas but I suspect it is. Using an external cblas however worked fine as far as I can tell. Francois
