Comment (by mark.chilenski@…):

 Upon further investigation, this issue appears to be from LAPACK being
 updated to lapackversion = 3.6.0 when building ATLAS. I made a local
 version of the portfile and dialed LAPACK back to 3.5.0 and SciPy appears
 to work now (though I'm waiting for the full test suite to complete).

 The changelog here: http://www.netlib.org/lapack/lapack-3.6.0.html notes
 that CGEGV is deprecated as of LAPACK 3.6.0. I suspect this means that the
 bug is in SciPy itself (i.e., that they shouldn't be referencing a
 deprecated function). If the maintainers agree with this logic, this
 ticket can be closed and I will submit a bug report with the SciPy devs.
 (Though perhaps they could consider adding an option to choose the LAPACK
 version when building ATLAS?)

 **For users who find this ticket looking for a short-term solution to get
 their SciPy to work with ATLAS**: I got it to the point that I can run
 "import scipy.linalg" by following the steps here:
 https://trac.macports.org/wiki/howto/InstallingOlderPort

 I just used the most recent revision ("`svn checkout
 https://svn.macports.org/repository/macports/trunk/dports/math/atlas`"),
 and modified line 15 to be "`set lapackversion       3.5.0`" and set the
 checksums at line 48-50 to:
 {{{
                     lapack-${lapackversion}.tgz \
                     rmd160  d803308ef28f3c6cffb051850823395e2cb29b6a \
