 From http://math-atlas.sourceforge.net/errata.html#osxlibname:

 = Problems with linking/missing LAPACK routines on OS X =

 OS X has a built-in version of ATLAS, and uses the standard names for
 them. They may be less up-to-date and/or have less libs than something you
 install yourself; in particular, if you have a Fortran compiler, you can
 build a full lapack library, which Apple does not currently provide, and
 so many users want to install the standard ATLAS. Unfortunately, when
 searching for libs the compiler looks in the system areas where apple
 keeps its ATLAS libs before looking in directories supplied by -L. This
 means that if you use -L and -l for your linking, you always get Apple's
 modified ATLAS, rather than the one you installed. There are two fixes for
 this problem that I know of. First, you can just link to the full name and
 path, rather than using -L. For instance, change something like:
    {{{
    gcc -o xtst test.c -L /home/whaley/TEST/ATLAS/build64/lib -lcblas
 -latlas
    }}}
 to:
    {{{
    gcc -o xtst test.c /home/whaley/TEST/ATLAS/build64/lib/libcblas.a \
           /home/whaley/TEST/ATLAS/build64/lib/libatlas.a
    }}}

 The only other trick I'm aware of is to rename your ATLAS libraries so
 that the Apple versions will not override them.


 Question: How to build scipy with this port libraries?
