Comment (by Peter.Danecek@…):

 Replying to [comment:10 wimmer@…]:
 > Let me note that I get the same problem for python 2.7 on OSX 10.8 when
 I install from source using "port install -s py27-scipy", instead of
 installing the prebuilt version. I looked into the problem, and figured
 out that the problem is due to the fact that scipy compiles all code with
 the macports gcc/gfortran, but when building the shared library object
 spline.so links with clang - hence the symbol {{{___ieee_divdc3}}} which
 is specific to gcc is not found. In fact, clang is used for all modules
 based on C-code (not Fortran code). You can see this in the attached
 build.log.

 Well, if this is really due to the fact that clang is used for linking,
 why this would happen on a 10.5 system?
 As far as I remember there is no clang, yet.
