Works here, and your log definitely indicate ATLAS has been found. The error message seem to indicate the wrong options are passed to gfortran to link the shared object. This is probably due to some confusion in the numpy build system which doesn't expect ATLAS on OS X. Francois On 12/10/15 15:1

Have you set SAGE_ATLAS_ARCH? Doing so is definitely not supported. We prefer using the accelerate framework on OS X. I have just upgraded xcode so I will give it a try. Francois On 12/10/15 13:20, Ian Hoffman wrote: This is my first post (and first time building Sage). I'm using El Capitan wit
