I don't know about that. What architecture are your working on? If
your Mac is Intel-based, you don't have to worry anyway, as by
default, only Intel images will be compiled.

If you have a PPC architecture, then the -arch flag will make sure
that an Intel image is compiled. But then you need an Intel-compiled
version of the GSL as well.

For what architecture did you compile the gsl?
