 Priority:  Normal            |  Milestone:
Component:  ports             |    Version:  2.3.4
 Keywords:                    |       Port:  py27-scipy atlas
------------------------------+--------------------------------
 I have installed py27-scipy @0.16.1_0 +gcc5 +atlas and atlas @3.10.2_2
 +gcc5. Both packages seem to have installed with no visible errors, but
 when I try to use scipy.linalg, the following exception occurs:

 {{{
 >>> import scipy.linalg

 ImportError:

 Possibly relevant: _cgegv_ appears to be listed as Undefined in
 _flapack.so:
 {{{
 $ nm
 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /site-packages/scipy/linalg/_flapack.so | grep _cgegv_
                  U _cgegv_
 }}}

 Is it possible that there is a mis-match between the MacPorts versions of
 SciPy and ATLAS? Or is something messed up in the build/linking step that
 causes _cgegv_ to not be found?

 For reference, I am running OS X 10.11.1 El Capitan and MacPorts 2.3.4.
 Thank you for your attention to this matter!
