Hi Nathan,

thanks for your quick reply.
Actually, numpy is installed even without scipy (see the install script around line 727). So it still get the same error even though INST_SCIPY= 0.

Just in case, this is where I got my gcc: http://www.astro.wisc.edu/~townsend/static.php?ref=mesasdk#Mac_OS_X

I'll create an issue on the bugtracker right now.

Cheers,

JC

A quick workaround for this error would be to delete the broken installation tree and then rerun the install script with INST_SCIPY=0.  This won't build LAPACK.
